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