FORMULA
G.f.: ( 4194304*(1+x)*(x^10 + 177134*x^9 + 46525293*x^8 + 1356555432*x^7 + 9480267666*x^6 + 19107752148*x^5 + 9480267666*x^4 + 1356555432*x^3 + 46525293*x^2 + 177134*x+1) ) / ( (x-1)^12 ). - R. J. Mathar, May 08 2015
From Amiram Eldar, Apr 25 2023: (Start)
a(n) = A017113(n)^11.
Sum_{n>=0} 1/a(n) = 2047*zeta(11)/8589934592.
Sum_{n>=0} (-1)^n/a(n) = 50521*Pi^11/62342309294899200. (End)
