comment Intuition for Multiple Summation becoming One Summation - Nothing too formal/rigorous please
Can you please give an example of "nice symmetries of the summands $A_{ij}$ in your answer that you talked about in your last follow-up (your follow-up to my follow-up 2)? I'm stuck on seeing why it's bad to write out multiple sums as one single sum.

Thanks so much! No problem. I can wait until next year. Can you please post your proof or link to it here as a second answer? I want to keep everything together. Happy new year!

Sorry for my late reply. Thanks so much! It's too bad I can't upvote more than once. I'll do it for your other first-rate posts. I have another follow-up to II. Can you please get back to me in your answer and not in comments? Merry Christmas!

Sorry for the late reply. +1. Thanks a lot. I made some minor edits and hope they're OK with you. I have some follow-ups that I put in my question. Can you please get back to me in your answer, and not in comments? Sub- and superscripts are too hard to read down here.

The many many subscripts and sums make things hard to read so slightly reformatted them.
