Presentation

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

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

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

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