Presentation

minimal degree	μ(G) = 25
transitive degree	μ_t(G) = 240

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

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