Numbers having four 3's in base 9. A43468

A triple of positive integers (n,p,k) is admissible if there exist at least two different multisets of k positive integers, {x₁,x₂,...,x_k} and {y₁,y₂,...,y_k}, such that x₁+x₂+...+x_k = y₁+y₂+...+y_k = n and x_1x_2...x_k = y_1y_2...y_k = p. For each n, let A(n) = {(p,k):(n,p,k) is admissible for some k}; then a(n) = |A(n)|. A334246
