[seqfan] Cutting a rectangle into two identical parts

This programming challenge:*
asks for the number of ways to cut a path through an m X n rectangle
such that one part, rotated 180 degrees and translated, coincides with
the other. (This is obviously only possible when mn is even.)

Is this sequence in the OEIS?  I couldn't find it.

* Technically not a challenge but a chrestomathy or "Rosetta stone",
hence the name of the site.
