Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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