This library contains every possible book of 410 pages, where each page has 40 lines of 80 characters drawn from 29 symbols. Each hexagonal room holds 640 books across 4 walls of 5 shelves.

The total number of distinct pages is 29³²⁰⁰ — a number with over 4,600 digits. For comparison, the number of atoms in the observable universe is a mere 10⁸⁰.

Somewhere in these infinite hexagons exists every poem ever written, every scientific discovery yet to be made, every love letter that could be composed, the precise account of your death, and the refutation of that account. The vast majority of books are gibberish — an ocean of noise in which the occasional coherent phrase is a miracle that the Librarians call a Vindication.

The Library has existed ab aeterno.

Use the Search feature to prove the Library's completeness. Enter any text — your name, a quote, a secret — and the algorithm will compute the exact hexagonal room, wall, shelf, volume, and page where that text resides. Then navigate there and read it.

Inspired by Jonathan Basile's libraryofbabel.info, the landmark digital Library of Babel. Basile's implementation uses a Linear Congruential Generator with modular inverses; this one uses an 8-round Feistel cipher operating at line level (29⁸⁰ possible lines).

Both approaches solve the same core problem: a reversible bijective mapping that makes the Library complete and navigable — given any text, we can compute its unique address without searching.
