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