Presentation

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

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

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