Presentation

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

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

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