Presentation

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

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

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