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