Presentation

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

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

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

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