Thompson group (finite)

Thompson group (finite)

In the mathematical field of group theory, the Thompson group "Th" (found by John G. Thompson) is a sporadic simple group of order

: 215 · 310 · 53 · 72 · 13 · 19 · 31: = 90745943887872000: ≈ 9 · 1016

The Thomspon group is a subgroup of the Chevalley group E8(F3),and therefore has a 248 dimensional representation over the field F3 with 3 elements, which was used to construct it.The centralizer of an element of order 3 of type 3C in the Monster group is a product of the Thompson group and a group of order 3, as a result of which the Thompson group acts on a vertex operator algebra over the field with 3 elements. (This vertex operator algebra contains the E8 Lie algebra over F3, giving the embedding of Th into E8(F3).)
