%N A055077 Multiplicity of Max{gcd(d, n!/d)} when d runs over the divisors of n!.
%C A055077 All terms are powers of 2.
%F A055077 It appears that a(n) = 2^A055460(n). - _Joerg Arndt_, Oct 06 2019
%e A055077 n=5, 5!=120, the set of gcd(d, 120/d) values for the 16 divisors of 120 is {1,2,1,2,1,2,1,2,2,1,2,1,2,1,2,1}. The maximum is 2 and it occurs 8 times, so a(5)=8.
