Butler  gave recurrence relations for computing the number N<inf>r</inf>(n) of r-valued (r = 2) switching functions of n variables realizable by a cascaded network of n - 1 r-valued cells. The cascades are assumed to have a fixed-input variable assignment. In this correspondence similar recurrence relations are presented for the number M<inf>r</inf>(n) of such cascade realizable functions that
