Presentation

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

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

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

GAP

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

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