[pmlwmlnt] Boustrophedonic Sator

6-by-6 grid of letters in a checkerboard of consonants and vowels.  Form 6 words of the form CVCVCV by alternately reading rows left-to-right then right-to-left.  Then, for redundancy (error detection), form six more words the same way vertically.

16 consonants BCDFGJKLMNPRSTVZ; 5 vowels AEIOU.

Apply the "English" substitutions c->ch (or maybe sh), g([ei])-> gh$1 (or maybe gu$1), e$->eh to induce the words to be pronounced consistently and distinctly.  Stress always goes on the middle syllable.

Example:

C	E	M	I	G	A
I	N	I	J	E	B
B	O	G	O	S	I
I	G	U	F	I	T
G	E	B	E	C	O
O	F	E	F	E	J

Perl source code

Same idea as previous, to encode data into words. This method has 113 bits per block.

A more general approach to this problem is to construct an error-correcting code in this mixed radix (16, 5, 16, 5,...) number system.
