Presentation

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

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

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