Presentation

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

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

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