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

GAP

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

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