Presentation

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

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

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