Presentation

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

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

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