Presentation

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

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

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