Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

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

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