A hyperbolic 3-simplex reflection group is a Coxeter group arising as a lattice in O C.3;1/, with fundamental domain a geodesic simplex in H 3 (possibly with some ideal ver- tices). The classification of these groups is known, and there are exactly 9 cocompact examples, and 23 non-cocompact examples. We provide a complete computation of the lower algebraic K-theory of the integral group ring of all the hyperbolic 3-simplex reflection groups.
