Presentation

minimal degree	μ(G) = 25
transitive degree	μ_t(G) = 640

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

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