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

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

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