Presentation

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

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

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