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)."""

Your request can't be satisfied:
- No available version of coq satisfies the constraints
No solution found, exiting

opam remove -y coq; opam install -y --show-action --unlock-base coq-hydra-battles.0.6truetrueNo files were installed.
