Presentation

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

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

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