The roadmap for rule table functionality contains an 8-cell neighbourhood called a range 2 von Neumann neighbourhood and a 12-cell neighbourhood called a range 2 diamond neighbourhood. This specification is different from what is currently implemented in Golly, as the range-2 von Neumann neighbourhood there corresponds to the "diamond" neighbourhood, and the 8-cell neighbourhood is instead a range-2 cross neighbourhood.
