We present an efficient method for computing the topological vertex symbols of zeolite frameworks. The algorithm gets its efficiency by dividing the problem into a sequence of quickly executed breadth-first searches. For small rings (fewer than eight vertices), we find there is no speed gain compared with a distance table approach, both methods executing quickly. The main benefits occur for large rings, or when no ring exists, a situation that forces a fruitless search over the full model domain. In this situation, our method is typically 60 times faster.
