Tables of letter sequences varying in order of approximation to English

Abstract

To obtain more complete tables of letter sequences varying in order of approximation to English than those generally available, sequences of zero through fourth-order approximation were computer-generated using tables of single-letter, digram, trigram, and tetragram frequencies. Two sets of tables are presented. One consists of 100 randomly selected 10-letter sequences of each of zero to fourth-order material. The other consists of 40 8-letter sequences of each type, selected with the restriction that no letter appear more than once in the sequence. © 1971, Psychon. Sci.. All rights reserved.
