Presentation

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

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

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

GAP

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

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