Presentation

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

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

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