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

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

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