Presentation

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

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

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