LuccioSamiComponents
LuccioSamiComponents[g] gives the Luccio–Sami components of the graph g.
LuccioSamiComponents[g, {v1, v2, …}]gives the components that include at least one of the vertices v1, v2, ….LuccioSamiComponents[{v -> w, …}, …]uses rules v -> w to specify the graph g.
Examples
g = Graph[{1 <-> 2, 2 <-> 3, 3 <-> 1, 4 <-> 5}];
