%C A115746 A109104! is a subsequence of this sequence. Also this sequence is a subsequence of A001013 and is not equal to A001013. 14! is the earliest term of A001013 which is greater than 1 and is not in the present sequence. All numbers of the form 2^m*3^n where m is positive and n is not greater than m are in the sequence. If p is prime and p+1 is in the sequence then p+1 is a term of the sequence A109104.
%e A115746 5760=2!*2!*2!*3!*5! so 5760 is in the sequence.
%Y A115746 Cf. A001013, A109104.
