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