Congruence Testing of Point Sets in 4 Dimensions

Computational Geometry 2016-03-24 v1

Abstract

Congruence between two n-point sets in 4 dimension can be checked in O(n log n) time. On the way to establishing this result, we revisit several parts of 4-dimensional geometry, such as angles and distances between planes, Hopf fibrations, and Coxeter groups.
