Presentation

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

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

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