Presentation

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

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

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