Conway triangle notation
If just done a bunch of math notation edits on Conway triangle notation. Please notice the difference between these two things:
 * $$ \sqrt(a+b)\, $$
 * $$ \sqrt(a+b)\, $$


 * $$ \sqrt{a+b\,} $$

and between these two things:


 * $$ (\frac{a}{b}) $$


 * $$ \left(\frac{a}{b}\right) $$

Disambiguation link notification for December 20
Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited Pythagorean triple, you added a link pointing to the disambiguation page Lattice. Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ* Join us at the DPL WikiProject.

Quick question what is the largest triple they have found? Also i think 1\3 +1\4+1\5 =1. Just wondering if you wanna hear about it Blackcat129 (talk) 08:00, 18 January 2018 (UTC)

Collatz number for Mersenne prime a-48
I finished calculating the Collatz number for the Mersenne prime a-48 (257885161-1). The value is 779044992. It took only 6039 minutes to verify. To make sure my calculation was correct, I did the first 30 Mersenne and they all matched to the list on OEIS.

I can send you the code if you want to validate it before updating the OEIS entry. Best regards. ReallyNiceGuy &#x2709; 16:53, 12 September 2022 (UTC)

 * ==Collatz steps for Mersenne Primes above a-45==
 * Above a-45, the ranking of Mersenne primes is provisional. So, the formal sequence of Mersenne primes is only verifiable up to a-45. Consequently, the formal sequence of Collatz steps for Mersenne primes is only verifiable up to s(a-45).
 * The comment section of OEIS A181777 has all 6 unranked steps for a-46 to a-51 and your value for a-48 is confirmed.
 * Apologies for a tardy reply but have been away visiting friends. Frank M. Jackson (talk) 17:12, 19 September 2022 (UTC)
