CONSTRUCTION OF STRONG AND ALMOST STRONG RATIONAL DIOPHANTINE QUADRUPLES
In this paper, we present four strong rational Diophantine quadruples and two almost strong rational Diophantine quadruples. This may give a basis to search for other families of strong and almost strong Diophantine quadruples with suitable properties.
Diophantine quadruples, strong/regular rational Diophantine quadruples, almost strong/irregular rational Diophantine quadruples, Pythagorean equation.
