Definition
This group, termed the Mathieu group of degree eleven and denoted is the subgroup of the symmetric group of degree eleven defined by the following generating set:
.
Note that since both the generating permutations are even permutations, is in fact a subgroup of the alternating group of degree eleven.
This is one of the five simple Mathieu groups, which form a subset of the sporadic simple groups. The parameters for the simple Mathieu groups are . There are also Mathieu groups for parameters , but these are not simple groups.
GAP implementation
Definition using the MathieuGroup function
The Mathieu group has order . Unfortunately, GAP does not assign group IDs for groups of such large orders. However, this group can be defined using the MathieuGroup function, as:
