Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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