Abstract

We investigate the basic interplay between the small k-valent vertex-transitive graphs of girth g and the (k; g)-cages, the smallest k-valent graphs of girth g. We prove the existence of k-valent Cayley graphs of girth g for every pair of parameters k > 2 and g > 3,improve the lower bounds on the order of the smallest (k; g) vertex-transitive graphs for certain families with prime power girth, and generalize the construction of Bray, Parker and Rowley that has yielded several of the smallest known (k; g)-graphs.
