#793 – GPT 5.6 Sol solves it's third Erdos Problem – Two primitives gone

OpenAI's GPT-5.6 Sol Ultra has solved Erdős Problem #793, a 50-year-old open problem about the asymptotics of 2-primitive sets, by producing a short and elegant construction that enhances the original method used by Paul Erdős.

Beautiful result on 2-primitive sets GPT-5.6 just solved another 50+ year old problem Erdős 793 GPT-5.6 Sol Ultra found me a solution to another Erdos problem not long after this one. Problem 793 asks about asymptotic of a 2-primitive set. GPT again came up with an extremely short and elegant construction that enhances original Erdos method used to prove a weaker result.
