- a(n) = Lucas(4n+2)+2, or 5*Fibonacci(2n+1)^2.at n=11A081067
- a(n) = Fibonacci(2*n+1) + Fibonacci(2*n-1) + 2.at n=23A092387
- a(n) = 5*Fibonacci(n)^2.at n=22A099921
- Let L(n) = Fibonacci(n-1)+Fibonacci(n+1) (cf. A000045, A000032); if n is even then a(n) = (L(n)+2)^2 otherwise a(n) = L(2*n)+2.at n=23A233000
