8 leads can detect many more keys if tri-state multiplexing (Figure 1, right) is used instead, which enables (n-1) × (n/2) keys to be detected with just n I/O lines. 8 I/O can detect 28 individual keys without ambiguity. Issues can occur with some combinations if two keys are pressed simultaneously.
The list of all single-letter-single-digit combinations contains 520 elements of the form [[{{letter}}{{digit}}]] and [[{{letter}}-{{digit}}]].. In general, any ...
2 of 5 barcode (non-interleaved) POSTNET barcode. A two-out-of-five code is a constant-weight code that provides exactly ten possible combinations of two bits, and is thus used for representing the decimal digits using five bits. [1] Each bit is assigned a weight, such that the set bits sum to the desired value, with an exception for zero.
The numbers less than () correspond to all k-combinations of {0, 1, ..., n − 1}. The correspondence does not depend on the size n of the set that the k-combinations are taken from, so it can be interpreted as a map from N to the k-combinations taken from N; in this view the correspondence is a bijection.

This is how the printer's key may appear in the first print run of a book. In this common example numbers are removed with subsequent printings, so if "1" is seen then the book is the first printing of that edition. If it is the second printing then the "1" is removed, meaning that the lowest number seen will be "2". [3]
The idea of factoring of large numbers can be applied to words, where a factor of a word is a block of consecutive symbols. [1] Thus, "cyclop" is a factor of "encyclopedia". In addition to examining sequences in themselves, another area to consider of combinatorics on words is how they can be represented visually.
