Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 4 generators on 28 points:

(5,6,8,7)(10,12)(21,22,25,23)(24,27,28,26);(1,2,4,3)(5,6,8,7)(14,17)(18,20)(22,23)(26,27);(9,10)(11,12)(13,14,16,17)(15,18,19,20)(21,23,25,22)(24,27,28,26);(1,3,4,2)(5,7,8,6)(13,15,16,19)(14,18,17,20)(21,24)(22,26)(23,27)(25,28)
