Reading 36 in NumGrid context
The 36 record above pulls directly from classical number theory plus NumGrid solver-derived puzzle statistics. What follows is the per-entity context — how 36 sits in the broader integer properties and number-guessing puzzles distribution and which underlying factors drive the headline numbers.
Every number on this page links back to classical number theory plus NumGrid solver-derived puzzle statistics; the methodology page describes the inputs, refresh cadence, and known limitations of the underlying data product.
Practical use of this page is in combination with the comparison and ranking pages elsewhere on the site, which surface the same data for 36’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.
