Presentation

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

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

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