In the mathematical field of group theory, the Monster group M or F 1 (also known as the Fischer-Griess Monster, or the Friendly Giant) is a group of finite order : = 808017424794512875886459904961710757005754368000000000 It is a simple group, meaning it does not have any normal subgroups except for the subgroup consisting only of the identity element, and M itself.

The finite simple groups have been completely classified (the classification of finite simple groups). The list of finite simple groups consists of 18 countably infinite families, plus 26 sporadic groups that do not follow such a systematic pattern. The Monster group is the largest of these sporadic groups and contains all but six of the other sporadic groups as subquotients.

The Monster (informally called Il Mostro in Italian) is a motorcycle designed by Miguel Angel Galluzzi and produced by Ducati Motor Holdings in Bologna, Italy since 1993. It is of the naked bike style, which is characterized by a sport bike with a fully exposed engine and frame. In 2005, Monster sales account for over half of Ducati's worldwide sales. Ducati motorcycles are best-known for their L-twin Desmodromic valve engines (also known as a 90° V-Twin) and tubular steel trellis chassis, both features designed by the late Fabio Taglioni (1920-2001).

The Monsters in the Morning is a radio show on WTKS Real Radio in Orlando, Florida, USA and XM Radio Channel 152 for the first four hours. It is a morning show that runs from 6 am-11 am EST.

The Monsters consist of Russ (Triple R) Rollins, Dirty Jim, Bubba "Whoop-Ass" Wilson, Rev. Daniel Dennis, Tuddle, Drunky The Bear and Tiffany. Occasionally, former members Jeff Howell & Bo "The Big Man" Rhodes will stop by.
