minimal degree	μ(G) = 29
transitive degree	μ_t(G) = 160

A minimal faithful permutation representation — 3 generators on 29 points:

(1,2,3,4,5)(6,7,9,11)(8,12,13,10)(14,15)(16,22)(17,19)(18,21)(20,24)(23,28)(25,27)(26,29);(6,8,9,13)(7,10,11,12)(15,19)(18,25)(20,26)(22,28);(14,16)(15,20)(17,23)(18,24)(19,26)(21,22)(25,29)(27,28)
