Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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