I found it on someone’s site but I didn’t link directly to it yet (but will on my followup post). The only identifiable name that I could find was “QYV”. So I gave a “Hat Tip” to QYV.

But I just found the answer starting from 9 zeros and worked my way down, not sure what QYV meant (probably forgot)….

Also not sure if it’s unique, but stepping back I’d say yes. If you assume all digits are A through J and A = #(0), B = #(1), etc., then you have 10 variables with 10 distinct answers so it would seem unique. I could have probably continued on down from 6 zeros and discovered whether it is or not, but I’m a busy man.

As that’s not a formal proof it holds little weight, but at least it answers it in my head. hehe.
