Presentation

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

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

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