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