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