Presentation

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

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

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

GAP

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

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