Presentation

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

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

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