Presentation

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

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

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