Presentation

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

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

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