Presentation

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

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

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