Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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