Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 336

A minimal faithful permutation representation — 3 generators on 26 points:

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