Testing for solutions, (1,4) and (109, 1138) are the only pair of positive integers found that satisfy the equation.

Extending the solution into the imaginary numbers, the number pairs (-4, 7i) and (-4, -7i) will also satisfy the equation. All other numbers found that satisfy the equation are fractional.
