Presentation

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

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

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