Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N T(n,k) = number of small equivalence classes of half full n-ary Boolean functions that contain 2^k functions.
%C Like A227725, but counting only small equivalence classes (sec) of half full Boolean functions, i.e. those with an equal number of zeros and ones.
