In mathematics, the nimbers, also called Grundy numbers, are introduced in combinatorial game theory, where they are defined as the values of nim heaps.
Description
Nimbers arise in a much larger class of games because of the Sprague–Grundy theorem.
The nimbers are the ordinal numbers endowed with a new nimber addition and nimber multiplication, which are distinct from ordinal addition and ordinal multiplication.
The minimum excludant operation is applied to sets of nimbers.
