Presentation

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

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

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

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