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