Presentation

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