Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

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

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