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