I did originally think that z (base 26) was 26, but then got the 0 value from:
http://www.mathsisfun.com/numbers/convert-base.php?to=letters
So what is right?
That is another reason that some puzzles and cryptosystems and word
sequences use base 32, with alphabet:
{0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z}
