minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 5 generators on 28 points:

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