%N A346631 Number of strongly asymmetric Boolean nested canalizing functions with n variables.
%H A346631 Yuan Li, Frank Ingram, Huaming Zhang, <a href="https://arxiv.org/abs/2001.09094">Certificate complexity and symmetric properties of nested canalizing functions</a>, arXiv:2001.09094 [cs.DM], 2020-2021
%F A346631 a(n) = n!((1+sqrt(2))^{n-1}-(1-sqrt(2))^{n-1})/sqrt(2).
%Y A346631 Comments from the Editors: It appears that this is essentially n!*A163271(n) (see also A052542), and also essentially 2*n!*A000129(n) (see also A215928). It also appears to match 2*A052580.
