Sequence http://oeis.org/A141534 is defined (apparently) as some simple
sums of the array of polygonal numbers A086270, and one would expect
this to match A006522 from A006522(3) on. The terms, however, fit a different
formula, and I have not been able to resolve this matter.
Does someone have an idea how the actual entries could match something
defined in terms of sums of polygonal numbers?
Currently this looks to me like a numerical error by the author.
The option to resolve this are:
i) mark the sequence as obsc and leave as is (a tutorial of how-not-to...)
iii) redefine as the 4th order matching polynomial
iv) Copy over terms A006522(3,4,5,6...) to match the definition.
