Presentation

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

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

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