COMMENTS
The sequence is only conjectured to be finite as of the publication in 1996, but there are definitely no more terms under 200000, so the conjecture seems extremely likely to be true.

EXAMPLE
A player can remove one seed from any pile, or remove two seeds from any pile and optionally split the remainder into two piles.
A pile of 3 is a P-position because whether the player to move takes 1 or 2, the next player takes 2 or 1 and wins.
