Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 4 generators on 24 points:

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