FORMULA

a(n) = Sum_{k=3..n} C(n,k)*A079261(k).

EXAMPLE

a(11) = [165,330,462,462,330,165,55,11,1] * [1,0,0,0,1,0,0,0,1] = 165+330+1 = 496.

MAPLE

bintrans:= proc(p) proc(n) add(p(k) *binomial(n, k), k=0..n) end end: f:= proc(n) if isprime(n) and modp(n, 4)=3 then 1 else 0 fi end: a:= bintrans(f): seq(a(n), n=1..40);
