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