• Source: Centered polyhedral number
  • In mathematics, the centered polyhedral numbers are a class of figurate numbers, each formed by a central dot, surrounded by polyhedral layers with a constant number of edges. The length of the edges increases by one in each additional layer.


    Examples


    Centered tetrahedral numbers
    Centered cube numbers
    Centered octahedral numbers
    Centered dodecahedral numbers
    Centered icosahedral numbers
    Stella octangula numbers
