Presentation

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

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

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

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