Presentation

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

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

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

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