The sporadic Mathieu groups are implemented in the Wolfram Language as MathieuGroupM11 MathieuGroupM12 MathieuGroupM22 MathieuGroupM23 MathieuGroupM24
All the sporadic Mathieu groups are multiply transitive . The following table summarizes some properties of the Mathieu groups, where

The Mathieu groups are most simply defined as automorphism groups of Steiner systems , as summarized in
the following table.
