Presentation

minimal degreeμ(G) = 25
transitive degreeμt(G) = 320

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

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