#### Table 1: grid size formats

FormatHow to interpret
xThe number x is a product of two primes. The grid’s width is the larger prime, the height the smaller.
(x)Same as x, but width and height are swapped.
x×yx is the width, y the height of the grid.
x by yx is the height, y the width of the grid.
x*yx is the total size of the grid, y the height.
x : yx is the total size of the grid, y the width.

#### Table 2: grid location formats

[x,y] Column, then row; top-left is [0,0]. Column, then row; top-left is A1. Row, then column; top-left is <0, 0>. Row, then column; top-left is 1, 1. Column, then row; bottom-left is (0,0). Column, then row; bottom-left is A-1. Row, then column; bottom-left is “0, 0”. Row, then column; bottom-left is 1/1. Cell number in scanline order; top-left is . Cell number in scanline order; top-left is 1st. Cell number in Cartesian order; bottom-left is #1. Cell number in Chinese reading order; top-right is 一. See Table 3 for Chinese numerals reference. The example shown here represents the number 47.

#### Table 3: Chinese numerals

 一 六 1 6 2 7 3 8 4 9 5 10

 Scanline order, also known as reading order, starts at the top-left, moves right across the row, and then continues likewise with each row from top to bottom.

 Cartesian order, also known as geometric order, starts at the bottom-left, moves right across the row, and then continues likewise with each row from bottom to top.

 Traditional Chinese reading order starts at the top-right, moves down the column, and then continues likewise with each column from right to left.
