Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 256

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

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

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