408 L R = 12181933

I watched these two coincidences in cipher 408 (solved), the letter L (twelfth in the alphabet), occurs 33 times, and the letter R (Eighteenth in the alphabet), occurs 19 times, again the date of birth of the primary suspect.... . Already in 340, total symbols for construction are 63, which is the sum of 12,18 and 33 (in this case there are several ways to reach the same value), as in the case of 408, what a coincidence huh!??
