Presentation

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

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

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

GAP

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

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