Computing the bridge length: the key ingredient in a continuous isometry classification of periodic point sets

Acta Crystallographica Section A, Volume 81, Issue 6, Page 427-437, November 2025.
We describe an efficient algorithm to compute the bridge length estimating the size of a complete isoset invariant, which classifies all periodic point sets under Euclidean motion.The fundamental model of any periodic crystal is a periodic set of points at all atomic centres.
