A figurate number which is constructed as an octahedral number with a square
pyramid removed from each of the six graph vertices ,
where
is an octahedral number and is a square
pyramidal number . The first few are 1, 38, 201, 586, ... (OEIS A005910 ).
The generating function for the truncated
octahedral numbers is
(3)
