The pair
11! + 18^2 = (18*351)^2
13! + 288^2 = (288*274)^2
represents a Sephira related to the Sephira of Bina. It starts in year 5501 and ends in year 5852. The length is 351 years, 27 times 13 years. Also, the length is 288 years, 16 times 18 years, from 5501 until 5789. So, also for Moshiach ben Yosef, there are two cycles, one 18 years and one of 13 years. They coincide when the count is 13*18, the year 5735, which is one year after the Yom-Kippur war.
In the previous post, we saw the parallel between the three cycles of 18 years after the year 5735, of Moshiach ben Yosef, until 5789, to three 19-year cycles of Moshiach ben David, until 5784.
A similar matter occurs with the cycles of 15 years, of Moshiach ben David, and 13 years of Moshiach ben Yosef. Three cycles of 13 years after the year 5735, is the year 5774. This was just as critical a year, as was the year 5771. But the cycle goes on, parallel to the 15-years until 5786, and 13 years after 5774 is the year 5787.
There are corollaries that are important to remember. One is that the Yom-Kippur war is for Moshiach ben Yosef, what is the six-day war for Moshiach ben David. The second is that the average of 5787 and 5786, equals the average of 5789 and 5784.
