Mistake
- The smallest number which can be written as the product of $4$ triples, each with the same sum ... The common sum is $137$. [Mauldron, AMM v88]
Correction
The citation is incorrect. The mathematician in question is in fact J.G. Mauldon.
It also needs to be noted that the cited result in the American Mathematical Monthly was in fact for $5$ such triples, not $4$.
