Presentation

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

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

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