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