Motivation
[edit]When it comes to structured information about mathematical functions, Digital Library of Mathematical Functions (Q24534) is a reference work that is widely used both within and beyond the Wikimedia ecosystem. Mapping to it in a systematic fashion by way of such a property would help improve Wikidata's coverage of functions too. Daniel Mietchen (talk) 22:21, 29 December 2022 (UTC)

Discussion
[edit]Support external identifier. I would also suggest properties like OEIS ID for people looking for other similar properties (external identifiers). John Samuel (talk) 07:58, 30 December 2022 (UTC)
Support Nice. ArthurPSmith (talk) 15:21, 31 December 2022 (UTC)

Support To discover the link to a formula one can hover over the circled "i" and look for "permalink" (Stating it here because I needed a moment to find this.). Looks like a great source. Toni 001 (talk) 08:32, 5 January 2023 (UTC)
Support An excellent resource, great find! 2A00:23C4:AF01:DA01:F0AE:7E64:9233:2629 10:13, 6 January 2023 (UTC)
