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

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

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