Presentation

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

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

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

GAP

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

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