%N Divisors of 24!.

%C 24! = 2^22 * 3^10 * 5^4 * 7^3 * 11^2 * 13 * 17 * 19 * 23;

%C the sequence is finite with A027423(24) = 242880 terms:

%C a(242880) = A000142(24) = A000197(4) = A010050(12) = 620448401733239439360000 is the last term.

%C Differs from the infinite sequence A080683 first for 169, 289, 338, 361 etc. - _R. J. Mathar_, Mar 17 2010
