Worked on improving the documentation for the OI-wiki/OI-wiki repository, focusing on the Math/Algebra Group-Theory section. Addressed documentation quality by correcting two typographical errors, updating the author attribution for transparency, and clarifying the explanation of the homomorphism theorem to enhance accuracy and reader comprehension. Employed Markdown for all edits, leveraging strong documentation skills to ensure the content was both precise and accessible. These changes contributed to the maintainability of the repository and reduced potential confusion for new contributors. The work supported community trust in the mathematical documentation and streamlined onboarding for future contributors engaging with the project.
