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