CycleStructure[p, x] returns the monomial in x[1], x[2], ..., x[Length[p]] that is the cycle structure of the permutation p.

CyclicGroupIndex[n, x] returns the cycle index of the cyclic group on n symbols, expressed as a polynomial in x[1], x[2], ..., x[n].

CyclicGroup[n] returns the cyclic group of permutations on n symbols.

Cyclic is an argument to the Polya-theoretic functions ListNecklaces, NumberOfNecklaces, and NecklacePolynomial, which count or enumerate distinct necklaces. Cyclic refers to ...

DegreeSequence[g] gives the sorted degree sequence of graph g.

Degrees[g] returns the degrees of vertex 1, 2, 3, ... in that order.

DegreesOf2Neighborhood[g, v] returns the sorted list of degrees of vertices of graph g within a distance of 2 from v.

DeleteFromTableau[t, r] deletes the last element of row r from Young tableau t.

DeleteVertex[g, v] deletes a single vertex v from graph g. Here v is a vertex number.
