Presentation

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

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

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

GAP

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

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