Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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