Talk:Dodecahedral number

I tried to edit the Properties section, for which I needed to upload a picture. Unfortunately I could not make it through all the red tape to upload the pucture and would up having to roll the edit back. Is there anywhere I can send the picture to load into this section? — Preceding unsigned comment added by Olthe3rd1 (talk • contribs) 01:08, 7 January 2024 (UTC)

Generating function

What's the significance of the generating function mentioned at the end of the article? The function given near the beginning of the article produces the sequence of dodecahedral numbers (because n=0, 1, 2, 3, 4, ... results in 0, 1, 20, 84, 220, ... as expected), but the generating function for x=0, 1, 2, 3, 4, ... produces the values 0, undefined, 146, 26.0625, 11.1111, ..., which don't have any obvious connection to dodecahedral numbers.
