Presentation

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

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

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

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