[seqfan] Peterson links in A959

[Alonso Del Arte]

There's a problem with both of the Ivars Peterson links in A000959. The MAA
link leads to a "page not found" message (complete with the equation 1 + 1
= 3), while the ScienceNews link leads to a seemingly irrelevant archive.
My Google searches seem to bring up only OEIS results and irrelevant pages.
Does anyone know where Peterson's MathTrek has been migrated to?
