  ## In mathematics
  
  172 is a part of a near-miss for being a counterexample to Fermat's last theorem, as $135^3$ + $138^3$ = $172^3$ − 1. This is only the third near-miss of this form, two cubes adding to one less than a third cube. It is also a "thickened cube number", half an odd cube $(7^3$ = 343) rounded up to the next integer.
