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