Presentation

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

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

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

GAP

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

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