Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 128

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

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