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