Presentation

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

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

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