Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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