Presentation

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

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

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

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