Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

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

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

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
