FORMULA
a(n) = n!((1+sqrt(2))^{n-1}-(1-sqrt(2))^{n-1})/sqrt(2).
CROSSREFS
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.
Sequence in context: A240403 A366734 A074598 * A307826 A239840 A052718
