# A Diophantine equation question?

```A couple of weeks ago, Neil forwarded to the list a set of several questions
I had asked regarding A116108 and a related sequence.  My main question was
(and still is) whether A116108 is finite and, if so, whether 41616 is the
final term.  Could anyone shed some light on this?

Thanks,

Dear Seqfans,  can anyone explain this sequence?

61 is obviously not in A000061 since that

I will extend A053169

Thanks for noticing this!

Neil

I was wrong - A000061 is not a simple list.

But assuuming all the terms are even, as Jon proposes, I extended
A053169 out to n=100

It would be nice to have a more precise
definition of A000061, which has been in the OEIS
