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.
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

(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
