Presentation

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

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

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

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