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