Presentation

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

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

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