Presentation

minimal degree	μ(G) = 29
transitive degree	μ_t(G) = 320

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

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

Polycyclic presentation:
