<p>Today I navigated to Wikipedia's &quot;<strong>Eclipse Cycle</strong>&quot; page and found that they had updated their table of eclipse cycles with many more named cycles. However, one particular cycle that I had recently wanted to find was still NOT among them. The cycle in question is the outcome of the eclipse equation &quot;<strong>11i-13s</strong>&quot; (in terms of &quot;inex + saros&quot; calculations). This eclipse cycle calculates to 84.0035 Tropical years (or 84 years + 1.28 days). I was surprised that it was not yet named because it is quite close to the same number of days as the orbital period of the planet Uranus. Hence my question - <strong>Is there a formal name for this 84 year eclipse cycle?</strong></p>

If it helps anyone - It is the same thing as a "triple Inex" minus a "hexon" = ~84 years

It is also the same as one "unidos" plus a "Metonic" cycle = 1039 lunations = ~84 years

I assume it is probably an unnamed cycle then - BTW there are a number of errors in the updated Wikipedia table - for those who perhaps help to edit such things...

What is the name of this eclipse cycle (if there is one)?

Today I navigated to Wikipedia's "**Eclipse Cycle**" page and found that they had updated their table of eclipse cycles with many more named cycles. However, one particular cycle that I had recently wanted to find was still NOT among them. The cycle in question is the outcome of the eclipse equation "**11i-13s**" (in terms of "inex + saros" calculations). This eclipse cycle calculates to 84.0035 Tropical years (or 84 years + 1.28 days). I was surprised that it was not yet named because it is quite close to the same number of days as the orbital period of the planet Uranus. Hence my question - **Is there a formal name for this 84 year eclipse cycle?**
