Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

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