Presentation

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

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

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