A rectangular grid of squares has $141$ rows and $91$ columns. Each square has room for two numbers. Horace and Vera each fill in the grid by putting the numbers from $1$ through $141 \times 91 = 12{,}831$ into the squares. Horace fills the grid horizontally: he puts $1$ through $91$ in order from left to right into row $1$ , puts $92$ through $182$ into row $2$ in order from left to right, and continues similarly through row $141$ . Vera fills the grid vertically: she puts $1$ through $141$ in order from top to bottom into column $1$ , then $142$ through $282$ into column $2$ in order from top to bottom, and continues similarly through column $91$ . How many squares get two copies of the same number?
