Abstract
Let $G$ be a non-amenable discrete group. We construct the paradoxical decomposition of $G$, by using the configuration equations under some conditions. This gives a positive answer to a question proposed by G. A. Willis. We find an upper bound for the Tarski number of a given group, by using configurations.
