Presentation

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

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

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

GAP

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

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