Presentation

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

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

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