Presentation

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

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

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