Presentation

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

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

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