Presentation

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

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

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