Presentation

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

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

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