Presentation

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

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

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