Presentation

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

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

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