Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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