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