Presentation

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

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

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