%N Number of PN-equivalence classes of canalizing functions with n variables.
%C PN-equivalence allows complementing the individual variables.
%D D. E. Knuth, The Art of Computer Programming, Vol. 4, Section 7.1.1 (in preparation).
%F For n>1, a(n) = 2*A000616(n) - 1 because the only self-dual examples occur when the function is a projection onto a single variable.
%Y See A102449 for definition and further references. Cf. A109460, A000616.
