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 prime.

用于研究可交换性至相干同伦同态的计算机代数系统

Python软件包ComCH是一种轻量级的专业计算机代数系统，它为知名对象，surjection和Barratt-Eccles运算提供模型，并在代数意义上参数化可交换的代数的产品结构。ComCH处理的此类代数的主要示例是空间的共链复合体，为此，它可以在所有黄金时期有效构造Steenrod同调运算。
