Presentation

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

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

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