Presentation

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

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

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