Presentation

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

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

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