Presentation

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

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

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

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

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