Hello. It looks like your 24 July 2005 edit to the Padovan sequence page added several identities, including

Can you tell me where you found that, or did you come up with it? I'd like to give an accurate citation in something I'm putting together.

PS Please excuse the odd username; it must have been made by someone else using my common email address.

I have no idea where I got those identities from. They are not difficult to derive. For example

Hello Gandalf61,

I would like to know a bibliographic reference for a math formula. I found this formula on Wikipedia, but no reference is given.

It's the 2nd formula ( is an Eulerian number):

in the chapter entitled "Formulas involving alternating sums" on the Wikipedia page:

https://en.wikipedia.org/wiki/Eulerian_number

I've looked at lots of (very complicated...) articles, but there's nothing obvious about this formula. Handbooks of Mathematics, etc. nothing, nothing, nothing...!

I saw that you were one of the contributors to this page. Can you provide a reference?

Thank you. RoyBetthe (talk) 10:12, 14 April 2024 (UTC)[reply]
