Explores integer solutions of a quaternary quadratic diophantine equation, highlighting connections with specific number sets.
This study explores a generalized quadratic Diophantine equation in four variables, building on classical approaches to highlight new connections with Krishnamurthy numbers and Leyland primes , considered here up to five-digit values. Different methods of working with the equation are outlined, and integer solutions are obtained through MATLAB computations.
