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

Polycyclic presentation:
