EXAMPLE
|
A(4,5) = A(5,4) = 1 because 5 encodes the game {0,1|}, where, because the option 1 dominates the option 0 on the left side, the zero can be deleted, resulting the game {1|}, the canonical form of the game 2, which is encoded as 4.

CROSSREFS
|
Row 0 is the characteristic function of A125991 (shifted one step). A(i, j) = A125999(i, j)*A125999(j, i). A126011 gives the A106486-encodings for the minimal representatives of each equivalence class of finite combinatorial games.
