Abstract
Let be a group. The permutability graph of subgroups of , denoted by , is a graph having all the proper subgroups of as its vertices, and two subgroups are adjacent in if and only if they permute. In this paper, we classify the finite groups whose permutability graphs are toroidal or projective-planar. In addition, we classify the finite groups whose permutability graph does not contain one of , , , , or as a subgraph.
