Presentation

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

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

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