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)(15,23,26,27)(16,19)(17,21)(18,22)(20,25,28,24);(14,19,22,21)(20,27,28,23);(2,4)(13,15,16,24,18,26,17,25)(14,20,21,23,22,28,19,27)
