doi: null

claim: "%N Sum of Fibonacci divisors of n^2 + 1. %C Conjecture: If the sum of the Fibonacci divisors of m^2 + 1 is a Fibonacci number, then this number belongs to the sequence A001906(n) = F(2n) where F(n) is the Fibonacci sequence."

The entry records these lines:
%N Sum of Fibonacci divisors of n^2 + 1.
%C A Fibonacci divisor of a number k is a Fibonacci number that divides k. (The divisor 1 is only counted once.)
%C Conjecture: If the sum of the Fibonacci divisors of m^2 + 1 is a Fibonacci number, then this number belongs to the sequence A001906(n) = F(2n) where F(n) is the Fibonacci sequence.
