My team has managed to solve a problem that&#x27;s sort of an Erdős problem. In the early sixties, Leo Moser asked about the value of some quantity. In a 1985 paper, Erdős commented that the quantity “seems likely” to be less than 1/4. It was known to be at most 2/7. After a long line of improvements by several teams, we were the first ones to go below 1/4. For those who are interested, https://www.sfu.ca/~vjungic/RamseyProjects/section-11.html describes the question.
