Presentation

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

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

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