כ"ת כת"ר

The Tikkun 14! + 420^2 = 295260^2 is right before Keter, and corresponds to Chochma. It can be written as

14! + 420^2 = (420*703)^2

We have seen these numbers before. One of the semiprime gematriot of כתר is 703. Whereas Keter is associated to 1000, Chochma is associated to 100. Further, 420 is כ"ת, Keter without Resh. We reach כתר through Chochma, in the merit of the Hasaga of כ"ת. The Rosh is added from above.
