Presentation

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

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

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