description: """
A formalisation of Burali-Forti paradox in system U (the
existence of an ordinal of ordinals is inconsistent), of Diaconescu
paradox (axiom of choice implies excluded-middle), of Reynolds paradox
(there is no set-theoretic model of system F) and Hurkens paradox in
system U (adapted by H. Geuvers to show the inconsistency of
Excluded-Middle in impredicative-Set Calculus of Inductive Constructions)."""

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-paradoxes.8.9.0truetrueNo files were installed.
