Presentation

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

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

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