a(n) = 2*(n+1)*binomial(n+2,4). A27777

a(n) is the number of subsets of {1..n} that contain exactly 2 odd and 3 even numbers. A330300

a(n) = partitions(n)*partitions(n+1). A90982

a(1) = 1, then partial products of ∏_n>=1 (p(n)/p(n-1)*p(n)/p(n-1)) = 1·1*1*(2)*(2)*(3/2)*(3/2)*(5/3)*(5/3)*(7/5)*(7/5)*...*; p = partition numbers, A000041 starting (1, 2, 3, 5, ...). A171646

First differences of 1/p(n), reciprocal of the number p(n) of unrestricted partitions of n (denominator). A272340
