Presentation

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

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

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