Discovered on 9 September 1996 by P. G. Comba at Prescott.
Arthur Cayley (1821-1895) started out as a practicing lawyer but in 1863 became a professor of mathematics at Cambridge. He published papers on many topics in algebra and geometry and was the founder, together with Sylvester, of the theory of algebraic invariants.Naming citation (20001111/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
