Binary subgroups of direct products
We explore an elementary construction that produces finitely presented groups with diverse homological finiteness properties – the binary subgroups, B(Σ, µ) < G1 ×· · ·×Gm. These full subdirect products require strikingly few generators. If each Gi is finitely presented, B(Σ, µ) is finitely prese...
