... induce maximal 2 -connected subgraphs of G, and are called the blocks (or 2-blocks) of G.Theblock–cutpoint tree is the graph defined on the union of the set of blocks and the set of cutpoints, with ... locally finite and 2 -connected. Proof: G(T ) is locally finite by condition 3. Clearly, any finite 3-block tree represents a 2 -connected graph. Let v and w be distinct vert...
