Presentation

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

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

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