Formula

From Wesley Ivan Hurt, Aug 22 2016: (Start)

G.f.: 59049*(1 + 59038*x + 9116141*x^2 + 178300904*x^3 + 906923282*x^4 + 1527092468*x^5 + 906923282*x^6 + 178300904*x^7 + 9116141*x^8 + 59038*x^9 + x^10)/(1-x)^11.

a(n) = 11*a(n-1) - 55*a(n-2) + 165*a(n-3) - 330*a(n-4) + 462*a(n-5) - 462*a(n-6) + 330*a(n-7) - 165*a(n-8) + 55*a(n-9) - 11*a(n-10) + a(n-11) for n>10.

a(n) = A008454(A016945(n)). (End)

From Amiram Eldar, Mar 30 2022: (Start)

a(n) = A016946(n)^5 = A016949(n)^2.

a(n) = 3^10*A016762(n).

Sum_{n>=0} 1/a(n) = 31*Pi^10/171421608960. (End)
