Presentation

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

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

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