Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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