Forum:Too many small categories

There are too many small categories, say, which contain lessequal to 3, or even 1 entries (well, this "3" is just a random choice of a "too small" category), such as Category:Cryptography-related numbers, Category:Song-Related Numbers, Category:Chess, Category:Powers of 10 with exponent bigger than 1,000,000, Category:Powers of 23, 122, Category:Numbers with radical 33, 74, 82, 174, 238, 266, 462, 798, 1919190, 4072530, Category:10^12, Category:PI Numbers, Category:Bigger than ℵ o, etc. (not a full list) Among them, the first three still seem OK; the powers and radicals go too far for categorization; and the final two are nonsense I think. &#123;hyp/^,cos&#125; (talk) 15:57, December 28, 2017 (UTC)
