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