Presentation

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

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

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

GAP

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

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