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