Presentation

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

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

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