Presentation

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

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

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