Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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