  2. Latin square - Wikipedia

    en.wikipedia.org/wiki/Latin_square

    A Latin square is said to be reduced (also, normalized or in standard form) if both its first row and its first column are in their natural order. [4] For example, the Latin square above is not reduced because its first column is A, C, B rather than A, B, C.

  3. Index of coincidence - Wikipedia

    en.wikipedia.org/wiki/Index_of_coincidence

    Sometimes values are reported without the normalizing denominator, for example 0.067 = 1.73/26 for English; such values may be called κ p ("kappa-plaintext") rather than IC, with κ r ("kappa-random") used to denote the denominator 1/c (which is the expected coincidence rate for a uniform distribution of the same alphabet, 0.0385=1/26 for ...

  4. Comparison of programming languages (syntax) - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_programming...

    In fixed format code, line indentation is significant. Columns 1–6 and columns from 73 onwards are ignored. If a * or / is in column 7, then that line is a comment. Until COBOL 2002, if a D or d was in column 7, it would define a "debugging line" which would be ignored unless the compiler was instructed to compile it. Cobra

  5. Propositional formula - Wikipedia

    en.wikipedia.org/wiki/Propositional_formula

    The predicate calculus goes a step further than the propositional calculus to an "analysis of the inner structure of propositions" [4] It breaks a simple sentence down into two parts (i) its subject (the object (singular or plural) of discourse) and (ii) a predicate (a verb or possibly verb-clause that asserts a quality or attribute of the object(s)).

  6. Lexical similarity - Wikipedia

    en.wikipedia.org/wiki/Lexical_similarity

    In the case of English-French lexical similarity, at least two other studies [7] [8] estimate the number of English words directly inherited from French at 28.3% and 41% respectively, with respectively 28.24% and 15% of other English words derived from Latin, putting English-French lexical similarity at around 0.56, with reciprocally lower ...

  7. Spreadsheet - Wikipedia

    en.wikipedia.org/wiki/Spreadsheet

    A typical cell reference in "A1" style consists of one or two case-insensitive letters to identify the column (if there are up to 256 columns: A–Z and AA–IV) followed by a row number (e.g., in the range 1–65536). Either part can be relative (it changes when the formula it is in is moved or copied), or absolute (indicated with $ in front ...

  9. Catalan number - Wikipedia

    en.wikipedia.org/wiki/Catalan_number

    The only known odd Catalan numbers that do not have last digit 5 are C 0 = 1, C 1 = 1, C 7 = 429, C 31, C 127 and C 255. The odd Catalan numbers, C n for n = 2 k − 1, do not have last digit 5 if n + 1 has a base 5 representation containing 0, 1 and 2 only, except in the least significant place, which could also be a 3.
