Neil James Alexander Sloane is an American mathematician best known for the On-Line Encyclopedia of Integer Sequences.Sloane received his Ph.D. in 1967 from Cornell University, for his dissertation on lengths of cycle times in random neural networks.Sloane did significant work for AT T Bell Labs on error-correcting codes.Sloane coauthored Sphere Packings, Lattices and Groups with John Horton Conway, giving him an Erdos number of 2.
His Erdős number is 2, since he coauthored Sphere Packings, Lattices and Groups with John Horton Conway. He has also collaborated with at least seven other Erdős coauthors. He is a winner of the Chauvenet Prize. In 2005 Sloane received the IEEE Richard W. Hamming Medal.Besides mathematics, he loves rock climbing and has authored two rock-climbing guides to New Jersey.
His research interests include sphere-packing, error-correcting codes, combinatorics, algebra, number theory, geometry, design of experiments. He also maintains the On-Line Encyclopedia of Integer Sequences.
