Presentation

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

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

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