Presentation

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

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

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