F(n) denotes the n-th Fibonacci number. I believe a(n) exists for all n > 0.

Table of n, a(n) for n=1..77.

(PARI)

a(n)=m=1; while((fibonacci(n)^2+fibonacci(m)^2)%(m+n), m++); m

vector(100, n, a(n))

Cf. A000045, A247937, A248032.

Sequence in context: A108123 A105954 A144252 * A318254 A002130 A089145
