A symmetric, anfireflexive relation S is a comparability graph ff one can assign a transitive orientation to the edges: we obtain a partial order. We say that S is a comparability graph with constraint C, a subrelation of S, if S has a transitive orientation including C. A characterization is given

For an undirected graph G the kth power G k of G is the graph with the same vertex set as G where two vertices are adjacent iff their distance is at most k in G. In this paper we prove that any LexBFS-ordering of a chordal graph is a common perfect elimination ordering of all odd powers of this grap

We develop a constant time transposition "oracle" for the set of perfect elimination orderings of chordal graphs. Using this oracle, we can generate a Gray code of all perfect elimination orderings in constant amortized time using known results about antimatroids. Using clique trees, we show how the
