Presentation

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

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

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