Presentation

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

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

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

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