OEIS Sequences

E.g.f. satisfies A(x) = ∑_n>=0 xⁿ/n! * exp(n/2·x) * A(x)^n/2. A273953

Number of essentially series oriented series-parallel networks with n elements and without multiple unit elements in parallel. A339288

Strong pseudoprimes to base 39. A20265

Triangular arrangement of solutions of φ(x) = 2ⁿ (n >= 0), where φ=A000010 is Euler's totient function. Each row corresponds to a particular n and its length is n+2 for 0 <= n <= 31, 32 for n >= 32. (This assumes that there are only 5 Fermat primes.) A58213
