In group theory, a topic in abstract algebra, the Mathieugroups are the five sporadic simple groups M11, M12, M22, M23 and M24 introduced by Mathieu (1861...

permutation representation on 23 points with point stabilizer the MathieugroupM22. M23 has 2 different rank 3 actions on 253 points. One is the action...
the classification of finite simple groups is a result of group theory stating that every finite simple group is either cyclic, or alternating, or belongs...
existence of the group J4. At the time it was thought that the full covering group of M22 was 6⋅M22. In fact J4 has no subgroup 12⋅M22.) Z. Janko (1976)...
three largest Mathieugroups, M22, M23 and M24. One particular source of confusion is that Fi24 is sometimes used to refer to the simple group Fi24′, and...

Most of the groups are named after the mathematician(s) who first predicted their existence. The full list is: Mathieugroups M11, M12, M22, M23, M24 Janko...

In the area of modern algebra known as group theory, the Mathieugroup M24 is a sporadic simple group of order 210 · 33 · 5 · 7 · 11 · 23 = 244823040...
sporadic simple group discovered in nearly a century: until then only the Mathieugroups were known, M11 and M12 having been found in 1861, and M22, M23 and...
