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

A minimal faithful permutation representation — 5 generators on 28 points:

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