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