Presentation

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

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

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