Mycielskian graph M15.
The Mycielskian graph sequence generates graphs that are triangle-free
and with a known chromatic number (i.e. the minimum number of colors
required to color the vertices of the graph).
Known properties of this graph (M15) include the following:
* M15 has a minimum chromatic number of 15.
* M15 is triangle-free (i.e. no cycles of length 3 exist).
* M15 has a Hamiltonian cycle.
* M15 has a clique number of 2.
* M15 is factor-critical, meaning every subgraph of |V|-1 vertices has
a perfect matching.
