Presentation

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

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

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