Epiphainein is a serial calculation and takes a few seconds to calculate the number of unreachable diagrams on a regular 8 x 8 board. With a decent machine it should take roughly 4 hours to calculate the same on a 10 x 10 board.","url_abs":"https://arxiv.org/abs/2202.00428v1","url_pdf":"https://arxiv.org/pdf/2202.00428v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"counting-unreachable-single-side-pawn","repo_url":"https://github.com/ctmcdo/epiphainein","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
