[seqfan] Re: A159580 easy, more

[N. J. A. Sloane]

Concerning A159577 and the associated sequences A159578 ... A159580 ...:

As Sean observed, the terms do not match the definiton.
The definition produces A116536, with related sequences A051838 and A196415.

But A159577 contains a UBASIC program. Can someone who understands
BASIC please read that program and explain what it does?

Then we can change the definition of A159577 etc to match 
the values of the terms.
