Abstract

The Python package ComCH, is a lightweight specialized computer algebra system that provides models for well-known objects, the surjection and Barratt-Eccles operads, parameterizing the product structure of algebras that are commutative in a derived sense. The primary examples of such algebras treated by ComCH, are the cochain complexes of spaces, for which it provides effective constructions of Steenrod cohomology operations at all primes.
