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