WebApr 20, 2014 · 1 Answer. Not all matrices have an inverse (see invertible matrix). The matrix will have an inverse if and only if its determinant is not zero, and does not have any common factors with the modular base. Thus, if we work modulo 26 as above, the determinant must be nonzero, and must not be divisible by 2 or 13.
