A228099 - cp's OEIS frontend

A228099 Triangle read by rows, T(n, k) = prime(1)^p(k,1)...prime(n)^p(k,n) where p(k,j) is the j-th part of the k-th partition of n, additionally T(0,0) = 1. The partitions of n are ordered such that partitions of n into r parts appear in lexicographic order previous to the partitions of n into s parts if s < r. (Fenner-Loizou tree).
