Presentation

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

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

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

GAP

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

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