Summary

Description
Numbered equivalence classes

Hasse diagram of the lattice of 67 subgroups of 4-bit nimber addition,
compare File:Z2^4; subgroups list.svg

This is a nonstandard Hasse diagram because some elements are displayed below elements that actually have a lower rank.
However, when two elements are linked by an edge the element with lower rank is displayed below the element with higher rank.
The rank of each element is expressed by the background color.

The ranks 0,1,2,3,4 correspond to the orders 1,2,4,8,16 of the subgroups.
