The New York Group Theory Cooperative was founded many years ago. It grew out of the New York Group theory Seminar and the very generous support from the National Science Foundation in the development of an innovative graphically driven group-theoretical software package Magnus. This was named after one of the founders of group theory, Wilhelm Magnus, whose picture is attached here. Have a look at its history, below.
New York Group Theory Seminar: The seminar meets Friday afternoons at the Graduate Center of the City University of New York. The current organizers are Sean Cleary, Olga Kharlampovich, Alexei Miasnikov, Gretchen Ostheimer, and Vladimir Shpilrain with some assistance from Gilbert Baumslag.
