Improved to Good Article status by David Eppstein (talk). Self-nominated at 01:11, 6 January 2022 (UTC).
Article listed as GA the day before DYK nomination and is long enough, cited, copyvio-free + neutral. Hook facts cited inline and in the article. QPQ done. Personally my preference is for ALT1, or a variant of ALT2 that gives a brief explanation of what Benford's law is, such as:
- ALT2b: ... that factorials are more likely to begin with small digits?
- though really all of the hooks are fine, it's just a matter of interestingness. eviolite (talk) 05:18, 6 January 2022 (UTC)
- Support ALT2b. 99% of main page readers will not know Benford's law so ALT2 just becomes "factorials obey something" (or "something obeys something" if they don't know factorials). People like me who actually know Benford's law would be surprised if factorials did not obey it. If ALT1 is used then link "one" to empty product. PrimeHunter (talk) 08:40, 6 January 2022 (UTC)
