Presentation

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

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

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