Presentation

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

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

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