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