Presentation

minimal degree	μ(G) = 29
transitive degree	μ_t(G) = 320

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

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