Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

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

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