A new infinite family of 4-regular crossing-critical graphs

Combinatorics 2024-04-16 v1

Abstract

A graph GG is said to be crossing-critical if cr(Ge)<cr(G)cr(G-e)< cr(G) for every edge ee of GG, where cr(G)cr(G) is the crossing number of GG. Richter and Thomassen [Journal of Combinatorial Theory, Series B 58 (1993), 217-224] constructed an infinite family of 4-regular crossing-critical graphs with crossing number 33. In this article, we present a new infinite family of 4-regular crossing-critical graphs.
