Presentation

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

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

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