Periodic discrete lines on the \(W \times H \) toroidal grid

This page shows a way to construct \(k\) cycles of homology class \((i,j)\) on the torus. This is not possible when the number of distinct needed vertices \(k(wj+hi)\) is higher than the number of vertices \(wh\)

<-- back the number of periodic forests

\(k(wj+hi)\) = \(wh\) =
