Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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