Presentation

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

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

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