Presentation

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

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

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