| Jul 1, 2015 at 7:16 | comment | added | Gordon Royle | For small $n$, I get the numbers of symmetric ones to be $4$, $44$, $716$, $24416$, which is a sequence not in the OEIS, nor are its obvious transforms (i.e. divide by 2 since we can swap 0/1). [Not sure why the question has 2 votes to close, as it seems perfectly reasonable to me.] | |
