Motivated by the desire to compute integral homology of arithmetic groups (and actions of Hecke operators thereon), I'll describe an algorithm to effectively cover locally symmetric spaces by balls. Attempts to efficiently cover lead to some interesting questions in computational geometry, also to be discussed. Joint work with Aurel Page.
