The discussion focuses on determining the largest integer n for which the Carmichael function λ(n) equals 2. It concludes that n must be of the form 6a, as all primes p not equal to 2 or 3 are congruent to 1 or 5 modulo 6. Additionally, it asserts that all primes less than or equal to the square root of n must be included in n, leading to the conclusion that no primes greater than 5 can satisfy the condition. Ultimately, the largest n for which λ(n) equals 2 is identified as 24. The conversation invites further questions on the topic of number theory.
