Presentation

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

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

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