Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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

GAP

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

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