Cyclic pseudo-{L}oupekine snarks
Abstract
In 1976, Loupekine introduced (via Isaacs) a very general way of constructing new snarks from old snarks by cyclically connecting multipoles constructed from smaller snarks. In this paper, we generalize Loupekine's construction to produce a variety of snarks which can be drawn with -fold rotational symmetry for (and often, odd), constructed as lifts of \emph{voltage graphs} with certain properties; we call these snarks \emph{cyclic pseudo-Loupekine snarks}. In particular, we discuss three infinite families of snarks which can be drawn with rotational symmetry whose smallest element is constructed from 3 snarks with 3-fold rotational symmetry on 28 vertices; one family has the property that the oddness of the family increases with . We also develop a new infinite family of snarks, of order for each odd , which can be drawn with -fold rotational symmetry and which are constructed beginning with a 3-edge-colorable graph, instead of a snark.
