Presentation

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

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

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