Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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

GAP

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

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