The Harada-Norton group of order 273030912000000 is one of the sporadic finite simple groups. It was discovered independently by Koichi Harada in 1976, and by Simon Norton in 1975, using different methods. It can be described as a centralizer of an element of order 5 in the Monster.
The HaradaNortonGroup() command returns a symbolic group representing the Harada-Norton group.
In the Standard Worksheet interface, you can insert this group into a document or worksheet by using the Group Constructors palette.
The GroupTheory[HaradaNortonGroup] command was introduced in Maple 17.
