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