Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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

GAP

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

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