Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

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

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