Presentation

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

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

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