Presentation

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

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

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