'''172''' ('''one hundred [and] seventy-two''') is the [[Natural number|natural number]] following [[171 (number)|171]] and preceding [[173 (number)|173]].

==In mathematics==
172 is a part of a near-miss for being a counterexample to Fermat's last theorem, as 135<sup>3</sup> + 138<sup>3</sup> = 172<sup>3</sup> &minus; 1. This is only the third near-miss of this form, two cubes adding to one less than a third cube.<ref>{{cite OEIS|A050787}}</ref> It is also a "thickened cube number", half an odd cube (7<sup>3</sup> = 343) rounded up to the next integer.<ref>{{cite OEIS|A050492|Thickened cube numbers}}</ref>
