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