Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 5 generators on 26 points:

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

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

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