Content Summary

Two forms are called concordant if there exist values of x and y that make both forms into squares at the same time. If they are not concordant, they are called discordant. For example, xx+yy and xxyy are discordant, while xx+yy and xx+7yy are concordant (e.g., x=3, y=4). Euler seems to get partial results.
