Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 6 generators on 26 points:

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