Presentation

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

A minimal faithful permutation representation — 4 generators on 26 points:

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