Presentation

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

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

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