• Number of partitions of n such that the number of even parts is a part or the number of odd parts is a part.at n=40A240576
• a(0) = 12, after which, if (2*a(n-1)) - 1 = product_{k >= 1} (p_k)^(c_k) then a(n) = product_{k >= 1} (p_{k-1})^(c_k), where p_k indicates the k-th prime, A000040(k).at n=31A246343
