Presentation

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

A minimal faithful permutation representation — 5 generators on 26 points:

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