Presentation

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

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

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