Presentation

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

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

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