Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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