Yeah, a seven sided polygon is referred to as a heptagon. However, the Septagon symbol has 21 sides. It has seven columns.
Sept is also a very common prefix for seven. In French, seven is in fact just that, sept (pronounced "set"). We also see it in numbers, IE million, billion, trillion, quadrillion, quintillion, sextillion, septillion...
