Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 5 generators on 26 points:

(1,2);(4,6)(7,8)(9,10)(11,12,16,19,15,18,24,26)(13,14,21,23,20,22,17,25);(3,4,5,6)(11,13,16,21,15,20,24,17)(12,14,19,23,18,22,26,25);(8,10)(11,14)(12,17)(13,19)(15,22)(16,23)(18,21)(20,26)(24,25);(12,18)(14,22)(19,26)(23,25)
