Presentation

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

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

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