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