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

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

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