Presentation

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

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

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