Presentation

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

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

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

GAP

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

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