Presentation

minimal degree	μ(G) = 29
transitive degree	μ_t(G) = 640

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

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