Presentation

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

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

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