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