An exploration of some properties of Kirby and Paris' hydra battles,
with the help of the Coq proof assistant. This includes the study of
several representations of ordinal numbers, and a part
of the so-called Ketonen and Solovay machinery (combinatorial
properties of epsilon0)."""

Dry install 🏜️

Dry install with the current Coq version:

Command
opam install -y --show-action coq-hydra-battles.0.6 coq.dev
Return code

Output
[NOTE] Package coq is already installed (current version is dev).
The following dependencies couldn't be met:
  - coq-hydra-battles -> coq < 8.16~ -> ocaml < 4.06.0
      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-hydra-battles.0.6
