| Description | We show that the square of every connected -free graph satisfying a matching condition has a 2-connected spanning subgraph of maximum degree at most 3. Furthermore, we characterise trees whose square has a 2-connected spanning subgraph of maximum degree at most k. This generalises the results on -free graphs of Henry and Vogler [7] and Harary and Schwenk [6], respectively. |
