%N Conway's subprime Fibonacci sequence, largest loop elements.
%C Similar to the Fibonacci recursion starting with a pair of positive integers, but each new nonprime term is divided by its least prime factor. Recursion enters a loop of length A214897(n), of which the largest element a(n) is prime (this sequence).
