Presentation

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

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

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