Presentation

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

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

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