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