I read a paper about the Cabibbo matrix and the CKM matrix.

The first one is a 2*2 real matrix and the other a 3*3 matrix with complex entries.

In this article i read that a n*n matrix has 2 n*n real degrees or freedom.

The unitarity (orthonormal basis) devides this number by 2.

I read that having n families gives 2n - 1 relations.

We have now (n - 1)(n - 1) real degrees of freedom

So the 2*2 matrix (with 2) families has only 1 real degree of freedom: the

Cabibbo angle.

Could you tell me what are these 2n-1 relations?

thanks
