## Abstract NebeskΓ½ in [12] show that for any simple graph with __n__ β₯ 5 vertices, either __G__ or __G^c^__ contains an eulerian subgraph with order at least __n__ β 1, with an explicitly described class of exceptional graphs. In this note, we show that if __G__ is a simple graph with __n__ β₯ 61 v
This paper studies the graphs for which the 2-edge connected spanning subgraph polytope is completely described by the trivial inequalities and the so-called cut inequalities. These graphs are called perfectly 2-edge connected. The class of perfectly 2-edge connected graphs contains for instance the
