FP₂ is the homological algebra version of ‘finitely presented’. For around 30 years it was open whether FP₂ is equivalent to ‘finitely presented’. Bestvina and Brady gave examples of non-finitely presented FP₂ groups in the late 1990s. Their examples are subgroups of finitely presented groups; in particular there are only countably many of them. I will discuss their construction and my new version which constructs a lot more groups.
