%N Number of factorizations of m^n into n factors, where m is a product of exactly n distinct primes and each factor is a product of n primes (counted with multiplicity).

%C Also number of ways to partition the multiset consisting of n copies each of 1, 2, ..., n into n multisets of size n.

%F a(n) = A257462(n,n) = A257463(n,n).

%e a(3) = 10: (2*3*5)^3 = 2700 = 30*30*30 = 45*30*20 = 50*27*20 = 50*30*18 = 50*45*12 = 75*20*18 = 75*30*12 = 75*45*8 = 125*18*12 = 125*27*8.

%Y Main diagonal of A257462 and of A257463.

%K nonn
