Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 64

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

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