Presentation

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

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

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

GAP

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

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