Presentation

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

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

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