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