"45 is the number of numbers..."
In terms of classical numerology, it most certainly is:


1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45

       In addition, is it too obvious to point out that

4 + 5 = 9:

          And that's not all:
 
 

F
O
R
T

9

          In sum, 45 is its own kind of apotheosis -- creating a point of union between numbers and text -- which makes it a number of completion that must be regarded as at least analogous to the celebrated 22.
