Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

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

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