Presentation

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

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

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

GAP

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

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