Square of degree of irreducible representation need not divide group order


It is possible to have a finite group G such that the square of one of its Degrees of irreducible representations (?) (i.e., the degree of an irreducible linear representation over an algebraically closed field of characteristic zero) does not divide the order of the group.

The simplest example is that of symmetric group:S3, a group of order 6 that has an irreducible linear representation of degree 2, even though 2^2 does not divide 6.
