Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 28 points:

(1,2,4,3)(13,14)(15,21,23,28)(16,24)(17,19)(18,22,27,25)(20,26);(5,6,7,10,8,9,11,12)(13,15)(14,18)(16,25,26,22)(17,23)(19,27)(20,28,24,21);(1,3,4,2)(6,9)(10,12)(14,19)(18,27)(20,24)(21,28)
