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