Presentation

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

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

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

GAP

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

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