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