Presentation

minimal degree	μ(G) = 25
transitive degree	μ_t(G) = 160

A minimal faithful permutation representation — 3 generators on 25 points:

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

Polycyclic presentation:
