Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 128

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

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

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

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