Two examples from the Wikipedia article  "Archimedean solid" —

Iain Aitchison said in a 2018 talk at Hiroshima that
the Mathieu group M24  can be represented as permuting
naturally the 24 edges  of the cuboctahedron.

The 24 vertices  of the truncated  octahedron are labeled 
naturally by the 24 elements of S4  in a permutahedron —

Can M24  be represented as permuting naturally
the 24 vertices  of the truncated octahedron?

Two examples from the Wikipedia article  "Archimedean solid" —

Iain Aitchison said in a talk last year at Hiroshima that
the Mathieu group M24  can be represented as permuting
naturally the 24 edges  of the cuboctahedron.

The 24 vertices  of the truncated  octahedron are labeled 
naturally by the 24 elements of S4  in a permutahedron —

Can M24  be represented as permuting naturally
the 24 vertices  of the truncated octahedron?
