'''Combinatorial dual graph, combinatorically dual graph''' — ''[[комбинаторно двойственный граф]].'' 

A [[graph, undirected graph, nonoriented graph|graph]] <math>\,G</math> is a '''combinatorial dual graph''' to a graph <math>\,G^{\ast}</math>, if there exists a one-to-one mapping <math>\,e: E(G) \rightarrow E(G^{\ast})</math> of the [[edge]] set of <math>\,G</math> onto the edge set of <math>\,G^{\ast}</math> such that <math>\,C</math> is a ''[[circuit]]'' of <math>\,G</math> if and only if <math>\,e(C)</math> is a ''cocircuit'' of <math>\,G^{\ast}</math>.
