Presentation

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

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

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