Presentation

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

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

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