A214896 Conway's subprime Fibonacci sequence starting with (382, 127). 0
382, 127, 509, 318, 827, 229, 528, 757, 257, 507, 382, 127 (list; graph; refs; listen; history; text; internal format)

COMMENTS

Similar to the Fibonacci recursion starting with (382, 127), but each new nonprime term is divided by its least prime factor. Sequence enters a loop of length 10 after 2 terms on reaching (382, 127).
