A game g is infinitesimal if -x < g < x for all positive numbers x, or equivalently if its left and right stops are both 0.

A partizan combinatorial game G is a left dead end if no subposition of G has any left options. In normal play, every left dead end is equal to a nonpositive integer. In misère play, the left dead ends have a more intricate structure; this sequence counts the misère-inequivalent left dead ends with birthday <= n.
