Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

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