Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 512

GAP

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

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