Presentation

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

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

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