Presentation

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

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

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