Presentation

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

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

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