description: """
This contribution contains data structures for ordinals
less than Gamma0 under Cantor and Veblen normal
forms. Well-foundedness is established thanks to RPO with status for
generic terms. This contribution also includes termination proofs of
Hydra battles and Goodstein sequences as well as a computation of the
length of the Goodstein sequence starting from 4 in base 2.
This work is supported by INRIA-Futurs (Logical project-team), CNRS
and the French ANR via the A3PAT project (http://www3.iie.cnam.fr/~urbain/a3pat/)."""

Dry install 🏜️

Dry install with the current Coq version:

Command
opam install -y --show-action coq-cantor.8.6.0 coq.dev
Return code
5120
Output
[NOTE] Package coq is already installed (current version is dev).
The following dependencies couldn't be met:
  - coq-cantor -> coq < 8.7~ -> ocaml < 4.05.0
      base of this switch (use `--unlock-base' to force)
Your request can't be satisfied:
  - No available version of coq satisfies the constraints
No solution found, exiting

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

Command
opam remove -y coq; opam install -y --show-action --unlock-base coq-cantor.8.6.0
