13# Profinite Crowell exact sequence over pro-C integer coefficients
15This is the profinite public entry point. It exposes the finite-coordinate Blanchfield--Lyndon
16maps, the completed Crowell exactness route, and the paper sequence
18```text
19N^ab(C) -> A_psi(C) -> Z_C[[H]] -> Z_C
20```
22and its finite-basis Blanchfield--Lyndon coordinate expression through
23`CrowellExactSequence.Profinite.MainTheorem`.
