Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

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

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