Presentation

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

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

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

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