Presentation

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

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

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

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

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