Presentation

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

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

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