Presentation

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

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

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