About NumberWiki

NumberWiki is a wiki of numbers. Every notable integer gets a permanent page with its mathematical properties, prime factorization, sequence membership, and alternate representations. Some numbers also have curated editorial notes covering their cultural, historical, or technical significance.

What numbers have pages?

The initial corpus includes:

• Every year from 1 to 2100.
• Every prime number under 100,000.
• A hand-curated set of famous and notable numbers.

Coverage will expand over time — the goal is dense coverage of small integers and sparse coverage of any larger number with notoriety.

How are classifications computed?

Every page runs through a classification engine that computes properties on the fly: primality is tested with deterministic Miller-Rabin (correct for all 64-bit integers), factorization uses trial division up to a large bound, and sequence membership is checked against precomputed sets for Fibonacci, Lucas, factorial, Catalan, and perfect numbers. Results are aggressively cached.

Reference series

• ASCII characters — codepoints 0–127, each linking to its number page.

Roadmap

Coming after v1:

• Live search-any-number page with on-the-fly analysis.
• Identifier detection: ISBN, Luhn (credit cards), UPC/EAN, phone-number heuristics.
• AI-generated overviews for notable numbers.
• Dense coverage of every integer 0–10,000.
• Number theory articles and topic pages.
