Presentation

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

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

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

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

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