Presentation

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

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

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