Presentation

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

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

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

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