Presentation

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

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

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