Presentation

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

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

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

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