Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 256

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

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

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