Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 512

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

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