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