Presentation

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

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

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