OEIS Sequences

Let Do(n) = A006566(n) = n-th dodecahedral number. Consider all integer triples (i,j,k), j >= k > 0, with Do(i) = Do(j) + Do(k), ordered by increasing i; sequence gives k values. A53019

Primes p whose period of reciprocal equals (p-1)/9. A56214

a(n) = coefficient of xⁿ*y^2·n+1/n! in log( ∑_n>=0 (n + y)^3·n * xⁿ/n! ). A360339

G.f. satisfies: A(x) = -1 + x + A(x)³ + 1/A(x)³. A228713
