• Indices of primes in sequence defined by A(0) = 33, A(n) = 10*A(n-1) + 43 for n > 0.at n=17A056255
• Expansion of e.g.f. exp(x)*(tan x + sec x)^3.at n=7A292759
• Square array A(n,k), n >= 0, k >= 0, read by antidiagonals, where column k is the expansion of e.g.f. exp(x)*(sec(x) + tan(x))^k.at n=62A322268
