OEIS Sequences

Numbers that have exactly 8 representations as a k-gonal number, P(m,k) = m*((k-2)*m - (k-4))/2, k and m >= 3. A321158

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

Shifts left when Stirling2 transform is applied twice. A7470

Numbers whose digital sum is equal to the sum of primes from their smallest to largest prime factor. A76406
