A (k; g)-graph is a k-regular graph with girth g. A (k; g)-cage is a (k; g)-graph with the least number of vertices. The order of a (k; g)-cage is denoted by f(k; g). In this paper we show that f(k + 2; g) ≥ f(k; g) for k ≥ 2 and present some partial results to support the conjecture that f(k1; g) < f(k2; g) if k1 < k2.
