%N Numbers n such that d_i(n) >= d_i(k) for k = 1 to n1, where d_i(n) is the number of infinitary divisors of n (A037445).
%C An infinitary (or FermiDirac) analog of the Ramanujan sequence A067128.
%C Between the smallest number b_k which is product of k distinct terms of A050376 and b_(k+1) all terms are products of k distinct terms of A050376.
%C Thus every subsequence of terms, having in FermiDirac factorization a fixed number of distinct factors from A050376, is finite.
%C These subsequences have cardinalities: 1, 4, 10, 21, 47, ...
