Presentation

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

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

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