Presentation

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

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

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