We can see also that, with the same premise, another conclusions are valid: columns 12, 14 and 15 are T. The column-8 operator (AND), shows Simplification rule: when p∧q=T (first line of the table), we see that p=T. With this premise, we also conclude that q=T, p∨q=T, etc. as shown by columns 9–15.
Two Latin squares, L 1 and L 2 of size n are isotopic if there are three bijections from the rows, columns and symbols of L 1 onto the rows, columns and symbols of L 2, respectively, that map L 1 to L 2. [1] Isotopy is an equivalence relation and the equivalence classes are called isotopy classes. A stronger form of equivalence exists.
In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.
The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 1 2 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 2 2 = 19.6 m; and so on. On the other hand, the penultimate equation becomes grossly inaccurate at great distances.
A Graeco-Latin square or Euler square or pair of orthogonal Latin squares of order n over two sets S and T (which may be the same), each consisting of n symbols, is an n × n arrangement of cells, each cell containing an ordered pair (s, t), where s is in S and t is in T, such that every row and every column contains each element of S and each element of T exactly once, and that no two cells ...

For odd square, since there are (n - 1)/2 same sided rows or columns, there are (n - 1)(n - 3)/8 pairs of such rows or columns that can be interchanged. Thus, there are 2 (n - 1)(n - 3)/8 × 2 (n - 1)(n - 3)/8 = 2 (n - 1)(n - 3)/4 equivalent magic squares obtained by combining such interchanges. Interchanging all the same sided rows flips each ...
