 OFFSET 0,2 COMMENTS Conjecture: a(n) is the largest prime factor of !n for all n > 2. - Sean A. Irvine, Apr 01 2023 LINKS Table of n, a(n) for n=0..23. EXAMPLE !4 = 1+1+2+6+24 = 34. The smallest value of n such that n! is divisible by 34 is 17!, so a(4)=17 CROSSREFS Sequence in context: A250545 A070917 A038757 * A169602 A092051 A065063 Adjacent sequences: A062546 A062547 A062548 * A062550 A062551 A062552 KEYWORD nonn AUTHOR Jonathan Ayres (jonathan.ayres(AT)btinternet.com), Nov 22 2001 STATUS approved
