Presentation

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

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

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