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