Charles R Greathouse IV, Table of n, a(n) for n = 1..10000

a(n)=n/A054494(n). [Corrected by Charles R Greathouse IV, Nov 05 2014]

a(10)=2 because 10/1=10 is not a Fibonacci number but 10/2=5 is.

(PARI) A010056(n)=my(k=n^2); k+=(k+1)<<2; issquare(k) || (n>0 && issquare(k-8))

a(n)=fordiv(n, d, if(A010056(n/d), return(d))) \\ Charles R Greathouse IV, Nov 05 2014

Cf. A000045, A010056, A005086, A037943.
