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