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