COMMENTS

These are codes for games which belong to the same equivalence class as the game {1} (i.e. the game 2).


LINKS

Table of n, a(n) for n=1..39.

EXAMPLE

Game {1} is encoded as 2^(2*1) = 4, thus 4 is the first term of this sequence. Also 5 belongs into this sequence, as it encodes game {0,1}, where, because the option 1 dominates the option 0 on the left side, the zero can be deleted, resulting the same game {1}.
