Presentation

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

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

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