Presentation

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

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

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

GAP

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

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