Find all integer solutions of y² = x³ - 432.
All numbers 1~99 Checked for X & Y simultaneously, i concur with the both previous comments
Column starting at A2, 1-99.
Row starting at B1, 1~99.
B2 = ($A2*$A2*$A2)-(B$1*B$1)
Drag this down to row 100 and column CV,
Carry out a conditional format of the entire grid to highlight all values equal to 432,
Only one was found at AK13, Y=12, X=36, (X=-36 Also)
