Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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