%N A328518 Number of terms k in A002182 that have A001222(k) = n.
%C A328518 If for every term t > 1 in A002182 there is some term t/p where p|t in A002182 then a(n) > 0 for all n.
%C A328518 The above hypothesis isn't true, e.g., t = A002182(815) is a counterexample. But it is surely true that a(n) > 0 for all n, see the graph of A112778. - _M. F. Hasler_, Jan 08 2020
%o A328518 (PARI) {my(v=v112778,c=Vec(0,vecmax(v)));for(i=2,#v,c[v[i]]++);c[1..-log(#c)\1]} \\ Does not include the leading a(0)=1. Discards log(#c) possibly inaccurate trailing terms. Vector v112778 must be defined, e.g., from b-file of A112778. - _M. F. Hasler_, Jan 08 2020
