Presentation

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

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

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