  Here I report about the modifications of and relations between graphic lambda
calculus, various formalisms which appeared under the name chemlambda and a
version of directed interaction combinators. This is part of the study and
experiments with the artificial chemistry chemlambda and the relations with
lambda calculus or interaction combinators, as described in arXiv:2003.14332
and available from the entry page at https://chemlambda.github.io/index.html
