A graph that is not cyclic is said to be acyclic. A cyclic graph possessing exactly one (undirected, simple) cycle is called a unicyclic graph. Cyclic graphs are not trees. A cyclic graph is bipartite iff all its cycles are of even length (Skiena 1990, p. 213). Unfortunately, the term … fixation bouteille de gaz camping-car
