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

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

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