Substring search
Find where any digit-string first appears in π — and list further occurrences. Digit-strings up to 9 digits long search instantly across the full 100B; digit-strings longer than 9 search within the first 100M.
Search 100 billion decimal digits of π through the lens of The First Verse of the Torah, Genesis 1:1.
Pi-Search is the research instrument for π exploration inside the TFV — The First Verse project. It exposes the decimal expansion of π through queries that match how the foundational research at The First Verse actually reasons about π: not just substring lookups, but sums, squared sums, gematria bridges, and position-aligned multi-condition queries.
Find where any digit-string first appears in π — and list further occurrences. Digit-strings up to 9 digits long search instantly across the full 100B; digit-strings longer than 9 search within the first 100M.
"Smallest N such that the first N decimals of π sum to X" — and the reverse. Range sums across any window from position A to position B.
Same operations but with each digit raised to the power 2 (the gematria value of the letter Bet) — the lens that uncovers the SGV→RGV bridge between The First Verse and π.
Type a Hebrew word; the tool computes RGV (Regular Gematria Value — the standard sum of letter values) and SGV (Small Gematria Value — the reduced single-digit form) and lets you search π for either number under any operation.
Up to five regular sums, five squared sums, and one sequence condition — all required to hold at the same starting position. This is the differentiating feature.
Click any returned position to see its prime factors, triangular / square / star indices, digital root, sum-of-thousands, and matches against canonical TFV values.
The mathematical patterns connecting The First Verse of the Torah, Genesis 1:1 to the decimal expansion of π are documented at length in the TFV foundational research. Pi-Search exists so any reader can verify these findings independently, search for adjacent patterns, and bring the instrument into their own study.
For the complete background — the original derivations, the cascade analysis, and the probability arguments — see the foundational π research at TheFirstVerse.com.
The 100 billion decimal digits of π that Pi-Search searches come from the first chunk of Peter Trueb's 2016 22.4-trillion-digit π computation, performed with the high-precision arithmetic engine y-cruncher and sponsored by DECTRIS. The complete computation is part of the publicly documented chronology of π calculation; the first one-trillion digits are hosted by the Internet Archive, a long-running non-profit digital library.
Anyone can download the same dataset Pi-Search uses, run their own integrity check, and recompute any finding here from first principles. The full archive item is at:
The archive item is signed off by these independent fixed points:
Sourcing public data is not enough; every research instrument should verify the data it runs on. Pi-Search performs four independent integrity checks against the corpus and publishes the results so they can be reproduced.
Every check below ran against the full 100-billion-digit corpus. Anyone can reproduce the methodology against their own download from the archive.org item; the verification script is published below.

run python integrity_check.py.
It re-runs all three checks and prints PASS/FAIL.

A central operation in TFV π research is summing the digits of π under a transform. The trivial case — Power-of-Aleph — is the ordinary sum (each digit contributes its own value). The next case — Power-of-Bet — squares each digit before summing. The naming follows the gematria of the Hebrew letters: Aleph = 1, Bet = 2, so "Power-of-X" means "raise each digit to the gematria of letter X."
The framework generalizes: Power-of-Gimel cubes each digit (Gimel = 3), Power-of-Daleth raises to the fourth power (Daleth = 4), and so on. Pi-Search currently exposes Aleph and Bet at launch; additional powers can be added with negligible precompute cost as findings surface that require them.
The Power-of-Bet operation is foundational to the SGV→RGV bridge: the first 82 (= SGV of The First Verse of the Torah, Genesis 1:1) decimals of π, each squared, sum to 2701 (= RGV of that same verse). The bridge between the small and standard gematria of the verse is mediated by the squared-sum operation on the decimal expansion of π itself.
Pi-Search counts decimal positions of π starting from the first decimal digit, not including the integer "3". So position 1 is the digit "1", position 2 is "4", position 3 is "1", and so on through π = 3.141592653…
All documented TFV findings (165 → 737, 611 → 2701, 82-squared → 2701, the position of "2701" at decimal #165, and the rest of the cascade) are stated and reproduced under this convention. If you prefer the alternative "include the leading 3" convention, simply shift every position by 1.
Recurring terms in TFV research and in the Pi-Search interface.
Every result is cross-verified against multiple independent π corpora. The digits we search come from rigorously sourced and independently published computations of π, and they have also passed our own comprehensive internal computational audit. Statistical estimation is never substituted for an actual computation; selectivity ordering only makes scans faster, never approximate.
Query parameters — window lengths, target values, sequences — are committed by the user before the search runs. Findings are reported as data, not as significance claims. Probability and look-elsewhere considerations are documented in the foundational TFV research, where they belong.

Install Python 3 and mpmath, place the corpus in a data/ sub-folder of the
repository, and run the script:
python -m pip install mpmath
python integrity_check.py
Script source: integrity_check.py. Output is PASS/FAIL for each of the three checks, plus a SHA-256 of your corpus so you can confirm you indexed the exact same bytes.
Position 1 is the first decimal of π — the digit "1" in 3.14159… — not the integer "3". All TFV-canonical findings on this page (165 → 737, 611 → 2701, …) are stated under this convention. If you prefer the alternative convention that includes the leading 3, shift every position by +1.
Power-of-Bet means raising each digit to the power 2 (the gematria value of the Hebrew letter Bet) before summing. The first 82 decimals of π under Power-of-Bet sum to 2701 — the regular gematria of The First Verse of the Torah, Genesis 1:1. This is the SGV→RGV bridge of the verse mediated by squaring.
The framework generalizes: Power-of-Gimel cubes (Gimel = 3), Power-of-Daleth raises to the fourth power, and so on. Pi-Search exposes Aleph and Bet at launch.
Observations, verified against the actual corpus. Pi-Search reports raw data. The interpretive and probabilistic arguments — what the findings mean, how to corrected for look-elsewhere, the priors that motivated checking these specific lengths and targets — belong to the foundational TFV research, not to this instrument.
Pi-Search currently exposes Power-of-Aleph (regular sum) and Power-of-Bet (squared sum) across the full 100B corpus. Future iterations include Power-of-Gimel (cubed) when findings call for it, deeper composite scan budgets, saved-finding registries for signed-in TFV members, and an open API for programmatic access — all of which compose with the current architecture without a redesign.
