Presentation

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

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

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

GAP

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

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