Presentation

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

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

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

GAP

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

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