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