Presentation

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

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

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