Peter Munn has shown that A309195(n) is even for n >= 1 (see that entry for a proof), so this sequence is well-defined. - N. J. A. Sloane, Jul 26 2019

The values I gave yesterday were wrong, caused by a bug in my program. Thanks to Peter Munn for pointing out that something was wrong. - N. J. A. Sloane, Jul 24 2019
