Presentation

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

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

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