• Same triangle as A106243, but with rows read in boustrophedon manner, i.e., in the order in which they were created.at n=41A106242
• Triangle read by rows from left to right. However, triangle is constructed in the boustrophedon way, reading alternately right to left and left to right. Top entry is 1. In all later rows, initial entry is 0, other entries are sum of previous entry in that row plus sum of two entries above it in previous row.at n=39A106243
• a(n) = floor(n*(n^3-n-3)/(2*(n-1))).at n=39A117561
• Numbers k that are the products of two distinct primes such that 2*k-1, 4*k-3, 8*k-7, 16*k-15, 32*k-31 and 64*k-63 are also products of two distinct primes.at n=20A177215
