Abstract
The Cartwright-Steger lattice is a group whose Cayley graph can be identiőed with the Bruhat-Tits building of PGLd over a local őeld of positive characteristic. We give a lower bound on the abelianization of this lattice, and report that the bound is tight in all computationally accessible cases.
