Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 1344

A minimal faithful permutation representation — 4 generators on 26 points:

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