Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 512

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

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