Presentation

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

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

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