Presentation

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

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

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