Presentation

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

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

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

GAP

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

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