Presentation

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

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

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