Presentation

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

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

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