The Manchester carry chain is a variation of the carry-lookahead adder [5] that uses shared logic to lower the transistor count. As can be seen above in the implementation section, the logic for generating each carry contains all of the logic used to generate the previous carries.
The California Job Case was a compartmentalized box for printing in the 19th century, sizes corresponding to the commonality of letters. The frequency of letters in text has been studied for use in cryptanalysis, and frequency analysis in particular, dating back to the Arab mathematician al-Kindi (c. AD 801–873 ), who formally developed the method (the ciphers breakable by this technique go ...
QWERTY, one of the few native English words with Q not followed by U, is derived from the first six letters of a standard keyboard layout. In English, the letter Q is almost always followed immediately by the letter U, e.g. quiz, quarry, question, squirrel. However, there are some exceptions.
This vocalic w generally represented /uː/, [3] [4] as in wss ("use"). [5] However at that time the form w was still sometimes used to represent a digraph uu (see W), not as a separate letter. In modern Welsh, "W" is simply a single letter which often represents a vowel sound. Thus words borrowed from Welsh may use w this way, such as:

The General Service List contains 2,000 headwords divided into two sets of 1,000 words. A corpus of 5 million written words was analyzed in the 1940s. The rate of occurrence (%) for different meanings, and parts of speech, of the headword are provided. Various criteria, other than frequence and range, were carefully applied to the corpus.
Sometimes, it is possible to "see" anagrams in words, unaided by tools, though the more letters involved the more difficult this becomes. The difficulty is that for a word of n different letters, there are n! (factorial of n) different permutations and so n! − 1 different anagrams of the word. Anagram dictionaries can also be used.
