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