摘要：

It is proved that each distance graph on a plane has an induced subgraph with a chromatic number that is at most 4 containing over 91% of the vertices of the original graph. This result is used to obtain the asymptotic growth rate for a threshold probability that a random graph is isomorphic to a certain distance graph on a plane. Several generalizations to larger dimensions are proposed. © 2016, Springer Science+Business Media New York.
