Presentation

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

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

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