Presentation

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

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

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