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