Presentation

minimal degreeμ(G) = 25
transitive degreeμt(G) = 144

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

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