  • To use , you first need to load the Graph Utilities Package using Needs["GraphUtilities`"].
  • A biconnected component is a maximal subgraph that has no cutpoint, where a cutpoint is a vertex v such that the subgraph becomes disconnected if v and all its edges are removed.
  • treats the input g as an undirected graph.
