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