Presentation

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

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

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

GAP

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

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