Presentation

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

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

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

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