Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 512

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

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

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