Presentation

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

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

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