Presentation

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

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

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