Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 5 generators on 26 points:

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

GAP

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

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