Definition: A connected graph such that deleting any two vertices (and incident edges) results in a graph that is still connected.
See also biconnected graph, k-connected graph, cut vertex.
Note: After Tomas Rokicki <email@example.com>, 24 December 2002.
Informally, there are at least three independent paths from any vertex to any other vertex. After Paul M. Sant, 6 Sep 2000.
