Presentation

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

A minimal faithful permutation representation — 5 generators on 26 points:

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