Presentation

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

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

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