Presentation

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

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

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