Presentation

minimal degree	μ(G) = 27
transitive degree	μ_t(G) = 192

A minimal faithful permutation representation — 6 generators on 27 points:

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