We establish a restriction on the covolumes of uniform lattices acting on X. When X is two-dimensional and has all links isometric to either a complete bipartite graph or the building for a Chevalley group of rank 2 over a field of prime order, we obtain further restrictions on covolumes.10 pages; main theorem extended to dimensions \geq 2; corollaries no longer require action without inversionsGroup Theory22D05, 20E42text
