→Table of three-particulars: fix table and add context
Line 2,184: Line 2,184:


=== Table of three-particulars ===
=== Table of three-particulars ===
Beyond the obvious range, 43-limit three-particulars become very sparse, hence S286/S289 is the first to break this pattern.
However, as it concerns intervals so small they can be considered commas, we do not extend the table further, as it's equal to {{sfrac| ([[96/95]])/([[289/286]]) | ([[289/286]])/([[290/287]]) }}.
(The 43-limit is picked due to 47/32 being close to 3/2, and 43/32 being close to 4/3, as well as to avoid spam.)
