Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 64

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

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