In this note, we study the condition of being one-ended for a particular class of discrete groups, namely groups acting freely and co-compactly on some CAT(0) square complexes. In particular, we furnish an algorithm that associates to a one-ended squared group another square complex which is “smaller” and more tractable than the one given by the definition of the group, in particular with nicer local connectivity conditions.

The power graph of a groupGis a simple graph with vertex setG, where two vertices are adjacent if one is a power of the other. Recently, we introduced the co-prime power graph as a generalization of the power graph. In this paper, we propose a modified and more appropriate version of the co-prime power graph and establish several results concerning its structure and properties.
