When Does a Square Board Split?

We study integer-board graphs whose edges have Euclidean length\(1/\lambda\) or \(\sqrt2/\lambda\); their moves form a union of leaperorbits and the components of the graph on \(\mathbb{Z}^2\) are the cosets of aGaussian ideal. Write \(\lambda^2=1/k\) or \(2/k\) in lowest terms a...
