Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

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

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