Presentation

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

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

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