An associative magic square is a magic square for which each pair of numbers symmetrically opposite to the center sum up to the same value. For an n × n square, filled with the numbers from 1 to n2, this common sum must equal n2 + 1. These squares are also called associated magic squares, regular magic squares, regmagic squares, or symmetric ...
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 ...
the indian numerals. A most-perfect magic square of order n is a magic square containing the numbers 1 to n2 with two additional properties: Each 2 × 2 subsquare sums to 2 s, where s = n2 + 1. All pairs of integers distant n /2 along a (major) diagonal sum to s.
The name "Latin square" was inspired by mathematical papers by Leonhard Euler (1707–1783), who used Latin characters as symbols, [2] but any set of symbols can be used: in the above example, the alphabetic sequence A, B, C can be replaced by the integer sequence 1, 2, 3.
The partial sums of the series 1 + 2 + 3 + 4 + 5 + 6 + ⋯ are 1, 3, 6, 10, 15, etc.The nth partial sum is given by a simple formula: = = (+). This equation was known ...
1973-1975 Ford F-250 Custom 4x4. "Highboy" is an enthusiast nickname adopted by a version of the sixth-generation F-series, pertaining to 1967-1977 F-250 4x4s. The largest 4x4s sold by Ford (the F-350 was not offered as a 4x4 until 1979), these trucks used the narrower frame rail spacing of the F-350 and a divorced transfer case (Dana 24, NP205 ...
The ninth generation of the Ford F-Series is a lineup of trucks that were produced by Ford from the 1992 to 1998 model years. The final generation of the F-Series to include a complete range of trucks from a half-ton F-150 pickup truck to a medium-duty F-800 commercial truck, this is the third generation of the F-Series body and chassis introduced for 1980.
Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...
