Presentation

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

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

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