Abstract
In this paper we discuss the action of \(SL(2,{\mathbb {C}})\) on hyperbolic 3-space using quaternions. And then we investigate suborbital graphs for the special subgroup of \(PSL(2,\mathbb {C})\). We point out the relation between elliptic elements and circuits in graphs. Results obtained by the method used are important because they mean that suborbital graphs have a potential to explain signature problems.
