Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

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

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