Bimonster group
From HandWiki
In mathematics, the bimonster is a group that is the wreath product of the monster group M with Z2:
- [math]\displaystyle{ Bi = M \wr \mathbb{Z}_2. \, }[/math]
The Bimonster is also a quotient of the Coxeter group corresponding to the Dynkin diagram Y555, a Y-shaped graph with 16 nodes:
- Script error: No such module "Dynkin".
John H. Conway conjectured that a presentation of the bimonster could be given by adding a certain extra relation to the presentation defined by the Y555 diagram; this was proved in 1990 by A. A. Ivanov a mathematician not the famous painter and Simon P. Norton.
