Presentation

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

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

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