Presentation

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

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

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