Presentation

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

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

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

GAP

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

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