Presentation

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

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

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