Presentation

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

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

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