Hello Seqfans,
Does anyone know the number of Hamiltonian cycles on a 2nx2n square
grid of points up to isomorphism?
I only found this sequence: A003763 Number of Hamiltonian cycles on 2n
X 2n square grid of points.
It starts: 1, 6, 1072, 4638576, ...
If we take the cycles up to isomorphism it should start: 1, 2, ...
Is there such a sequence on the OEIS? Does anyone know the next number?
I am working on a blog entry where it would be nice to have a reference
to this sequence.
Best, Tanya Khovanova
