In mathematics

172 is a part of a near-miss for being a counterexample to Fermat's last theorem, as 1353 + 1383 = 1723 − 1. This is only the third near-miss of this form, two cubes adding to one less than a third cube.[1] It is also a "thickened cube number", half an odd cube (73 = 343) rounded up to the next integer.[2]
