Presentation

minimal degree	μ(G) = 25
transitive degree	μ_t(G) = 320

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

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