Presentation

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

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

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