In contrast to prime power factorization of n! where maximal prime does not exceed n, in the considered factorization of n!, the maximal A050376-factor could be much greater than n. For example, for n=18, it is 65536.
Essentially, a(n) is A177334 with duplicates removed. - Ivan Neretin, May 31 2016
EXAMPLE
81 is in the sequence, since 9! = 2*4*5*7*16*81.
