Presentation

minimal degree	μ(G) = 29
transitive degree	μ_t(G) = 1280

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

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