The 9-quine is the smallest quine in chemlambda which does not have a termination node. There exist smaller quines if the termination node is admitted. For example the chemlambda equivalent of a quine from Interaction Combinators which appears in Lafont’ foundational article.
As you see this version is conservative and there are no enzymes.
I shall come back with a post which explains why and how the 9-quine dies. It is of course due to the conflicts in chemlambda, see the examples from the page on chemlambda v2.
