COMMENTS

Prime p divides a((p-1)/2) for p = {29,89,101,181,229,...} = A047650[n] Primes for which golden mean tau is a quadratic residue or Primes of the form x^2 + 20y^2. - Alexander Adamchuk (alex(AT)kolmogorov.com), Aug 07 2006

FORMULA

a(n)=(1/275)*(F(5n+1)+4*F(5n+2)-(-1)^n*(55/2)*F(3n+1)-110*F(n+2)+175/2) where F(n)=A000045(n)
