Reading 164 in NumGrid context
The 164 record above pulls directly from classical number theory plus NumGrid solver-derived puzzle statistics. What follows is the per-entity context — how 164 sits in the broader integer properties and number-guessing puzzles distribution and which underlying factors drive the headline numbers.
The methodology behind every numeric value on this page is publicly documented on the classical number theory plus NumGrid solver-derived puzzle statistics portal and described in detail on this site’s methodology page. Refresh cadence varies by underlying series; the page surfaces the as-of date for each number so readers can trace any figure back to the source release.
Practical use of this page is in combination with the comparison and ranking pages elsewhere on the site, which surface the same data for 164’s peers within positive integers within the NumGrid target pool. A single-entity reading without peer context can be misleading when an entity is an outlier on one axis but typical on another.
