Presentation

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

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

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