Presentation

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

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

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