Fischer groups are a set of sporadic simple groups discovered by Bernd Fischer in the late 1960s, known for their intricate structures and roles within the classification of finite simple groups. These groups, specifically the three Fischer groups Fi22, Fi23, and Fi24, are among the 26 sporadic groups and are characterized by their unique properties and symmetry relations.

Sporadic Simple Groups

Finite simple groups are the building blocks of all finite groups, analogous to prime numbers in number theory, and they are fully classified by the monumental achievement known as the Classification of Finite Simple Groups. This classification consists of several infinite families and 26 exceptional groups known as the sporadic groups, with the Monster group being the largest among them.

Intricate Structures

The Classification of Finite Simple Groups is a monumental achievement in mathematics, providing a comprehensive list of all possible finite simple groups, which are the building blocks of all finite groups. This classification includes 18 infinite families and 26 sporadic groups, and its proof spans thousands of pages contributed by numerous mathematicians over several decades.
