Daily solutions of Fish messages at G. C. & C. S. reflect a
background of British mathematical genius, superb engineering ability, and
solid common sense.
Each or these has been a necessary factor. Each could have been
overemphasised or underemphasised to the detriment of the solutions; a remarkable
fact is that the fusion of the elements has been apparently in perfect
proportion. The result is an outstanding contribution to cryptanalytic science.

Fried. There is little difference therefore between the mathematics at Arlington
