Presentation

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

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

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