Presentation

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

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

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