Moreover, as the length of the required phrase or sentence grows, the number of possible letter sequences of that length grows exponentially, and grows much faster than the number of possible meaningful sequences, so that the probability of finding a functional sequence via a random search diminishes precipitously with necessary sequence length. Denton noted that whereas for every meaningful sequence of English letters 12 letters long there are one hundred trillion (or 1014) corresponding gibberish sequences, for every meaningful sequence of English letters 100 letters long there are 10100
