Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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