Any representation of a  nite Lie group can be expressed as a direct sum of this kind of representations, and the number of this kind of representations of a group is equal to the number of conjugacy classes of the group.
The number of this kind of degree-n polynomials mod 2 is equal to the number of binary Lyndon words with length n. Any representation of a  nite Lie group can be expressed as a direct sum of this kind of representations, and the number of this kind of representations of a group is equal to the number of conjugacy classes of the group. This term is used to describe ring ideals not expressible as the   intersection of two other ideals. x2 + 1 is this over the integers, but is not this mod 2 because it is the product of x + 1 with itself. For ten points, identify this term used to describe polynomials that cannot be factored.
