Presentation

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

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

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

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

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