Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

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

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