What is the binary rank of NN^T for generalized quadrangle G(2,t) where N is incidence matrix of G(2,t) and N^T is transpose of N?

I try to find rank of  NN^T for generalization of quadrangles. But I am not sure about it. If t is odd, rank is 5 according to me. When t is even, statement is different. Is there any programme...
