Presentation

minimal degreeμ(G) = 25
transitive degreeμt(G) = 160

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

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