Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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