Presentation

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

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

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

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