+ On the basis that A = 1, B = 2, C = 3 ..., Z = 26, then ODD (23) is odd. Note that mathematically odd + odd = even and ODD (23) + ODD (23) = EVEN (2 * 23). [Homewood]

+ If you add the successive digits of π, then the first prime number total is 23. Note that the final digit added is 9 and 23 is the 9th prime number. [Homewood]

+ Is there a longer word (with more than 23 letters) that does not contain the letter 'e' than transubstantiationalist? [Homewood]
