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