Presentation

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

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

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

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