Presentation

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

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

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