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