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.

A. Karttunen, Scheme-program for computing this sequence.

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|}.

CROSSREFS

Row 5 of A126000.

Sequence in context: A193964 A099897 A050251 * A080610 A047175 A133632
