synopsis: "Exploration of some properties of Kirby and Paris' hydra battles, with the help of Coq"
description: """
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)."""

The following dependencies couldn't be met:
- coq-hydra-battles -> coq < 8.16~ -> ocaml < 4.12
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:
opam remove -y coq; opam install -y --show-action --unlock-base coq-hydra-battles.0.9truetrueNo files were installed.
