Presentation

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

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

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