### Abstract

We present techniques for obtaining a generating function for the diagonal T<inf>2n,n</inf> of the triangle formed from the coefficients of a generating function G(x) raised to the power k. We obtain some relations between central coefficients and coefficients of the diagonal T<inf>2n,n</inf>, and we also give some examples.
