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