- directed interaction combinators vs. chemlambda chemistries, associated with arXiv:2005.06060:

- Alife properties of directed interaction combinators vs. chemlambda

- extra: 16 animations which supplement arXiv:2005.06060

- explore chemlambda and IC quine graphs (first version, with no article attached):

Interaction combinators and chemlambda quine graphs

- tools to find quine graphs and more examples:

How to test a quine

- molecules laboratory: input your own molecules

The quine lab - detailed explanation of the ouroboros quine, inspired from the lambda calculus predecessor term:

The Ouroboros - untyped lambda calculus terms can be reduced in chemlambda:

Lambda calculus to chemlambda parser - more than 250 animations from simulations, with comments and the possibility to run them in js:

Project hapax, aka "made of money": a remake of chemlambda (and arbitrarily many other graph rewrite systems) as a conservative graph rewrite system, with the help of tokens and permutation based automata. Articles and demos:

Special thanks to the other authors of chemlambda repositories listed here. Their work greatly enhanced this project and also validated it. The discussions, see those listed here or in the issues of the other repositories, helped very much to clarify the subject.
