Presentation

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

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

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