Presentation

minimal degree	μ(G) = 27
transitive degree	μ_t(G) = 96

A minimal faithful permutation representation — 4 generators on 27 points:

(1,3)(2,6)(4,7)(5,8)(10,17)(15,18)(16,24)(20,23)(25,26,27);(2,5)(3,7)(9,12)(10,16,17,24)(11,19,13,21)(14,22)(15,20)(18,23)(26,27);(1,2)(3,8)(4,5)(6,7)(9,11,14,13)(10,15)(12,21)(16,23,24,20)(17,18)(19,22);(2,5)(3,7)(9,10,11,15)(12,20,21,16)(13,18,14,17)(19,24,22,23)
