This rewrite system is a working version of anharmonic lambda, or kali (older: kaleidoscope). The goal is to find a version which contains both chemlambda v2 and em-convex. All rewrites are chosen from emergent algebra considerations. See this tool to choose DIST rewrites. It is amazing that it can reduce lambda terms. It has also a brutal form of eta reduction, related to the Reidemester 2 moves. Work in progress because as the name tells, a completely symmetrical version should have 24 nodes.
