User talk:Peter Luschny/Nimber

Hi.
I've just found, that the subgroups of nimber addition have an interesting feature: The subgroups of Z2^n belong to 2^n equivalence classes, and the number of these equivalence classes rank by rank corresponds to a row of Pascals triangle. At least, that's what I have shown till n=4 at the moment: http://en.wikiversity.org/wiki/Subgroups_of_nimber_addition
