Presentation

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

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

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