| Apr 16 at 13:44 | comment | added | Peter Taylor | FWIW, the question of whether an integer sequence or table has been studied before can often be answered with a search on OEIS. Here $m\diamond n$ corresponds to A305720, so other people have thought about it, but there are no references given to published papers. | |
| Apr 12 at 16:07 | comment | added | Gerald Edgar | However note: A post which is off topic will not magically become on-topic simply by adding "Has this been done before?" We sometimes also see this ploy in hsm.stackexchange.com | |

| Jan 17 at 9:58 | comment | added | JP McCarthy | @LSpice thank you: I just made up the notation on the spot, so just went for an "at hand" notation. | |

TeX note: it will produce very large spacing, so maybe you are intentionally avoiding it, but TeX forgets that + is a binary operation when it is \boxed, and \mathbin reminds it: $r\boxed+s$ vs. $r\mathbin{\boxed+}s$ $r\boxed+s$ vs. $r\mathbin{\boxed+}s$. But perhaps just $r \boxplus s$ r \boxplus s (although there is only $r \boxtimes s$ r \boxtimes s, not a boxed star, as far as I know) will do?

| Jan 16 at 16:11 | comment | added | John Bentin | Not your question, I know, but a primary reason to study any proposed new structure is that it is interesting. The richness of much of mathematics arises from the basic operations interacting through simple laws: in particular, the distribution of multiplication over addition and the associative law for both operations. Do your operations conform to such laws? | |
