Presentation

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

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

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