• Expansion of cosh(x)*cosh(log(1+x)).at n=7A009178
• Triangle read by rows: row n gives coefficients C(n,j) for a Sheffer sequence (binomial-type) with lowering operator (D-1)/2 + T{ (1/2) * exp[(D-1)/2] } where T(x) is Cayley's Tree function.at n=49A135494
• Expansion of f(-x^6)^3 / (f(-x^4)^2 * psi(x)) in powers of x where phi(), f() are Ramanujan theta functions.at n=35A262152
