Presentation

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

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

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