Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

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

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