Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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