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