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