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

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.0.4truetrueNo files were installed.
