Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 3 generators on 24 points:

(1,2,4,6,5,8,3,7)(9,10)(11,17,18,14)(12,20,22,15)(13,16)(19,24)(21,23);(2,6)(3,4)(7,8)(10,14)(15,23)(16,17)(20,24);(10,15)(11,18)(14,23)(16,20)(17,24)(19,21)
