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

A minimal faithful permutation representation — 3 generators on 28 points:

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