Let N >= 2 and c(< N ) be, respectively, even and odd numbers. The chordal ring mixed graph CRM(N, c) is a mixed graph with vertex set V = Z_N (all arithmetic is modulo N ), with arcs i -> i + 1 (forming a directed cycle) and edges i ∼ i + c if i is even (and, hence, i ∼ i - c if i is odd, forming the ‘chords’).
