RobertsonGraph returns a 19-vertex graph that is the unique (4, 5)-cage graph.

Runs[p] partitions p into contiguous increasing subsequences.

SelfLoopsQ[g] yields True if graph g has self-loops.

SignaturePermutation[p] gives the signature of permutation p.

SimpleQ[g] yields True if g is a simple graph, meaning it has no multiple edges and contains no self-loops.

SmallestCyclicGroupGraph returns a smallest nontrivial graph whose automorphism group is cyclic.

Spectrum[g] gives the eigenvalues of graph g.

StronglyConnectedComponents[g] gives the strongly connected components of directed graph g as lists of vertices.

SymmetricGroup[n] returns the symmetric group on n symbols.

TableauQ[t] yields True if and only if t represents a Young tableau.
