Abstract
We propose a classification of the solutions of the graded reflection equations to the vertex model. We find twelve distinct classes of reflection matrices such that four of them are diagonal. In the non-diagonal matrices the number of free parameters depending on the number of bosonic () and fermionic () degrees of freedom while in the diagonal ones we find solutions with at most one free parameter.
