Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 5 generators on 24 points:

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