Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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