Presentation

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

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

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