[seqfan] Re: Overview of sequence arising from binary quadratic forms

[Peter Luschny]

As a satellite to the Wiki page of Neil I've written a small program
that will handle the different cases under a single interface.

It is written in Sage/Python and based for the indefinite quadratic
forms on a program by Will Jagy.

Suggestions for improvements and extensions are welcome. Please report
bugs to me immediately.

Peter

P.S.  Since it calculates positive numbers represented by a binary
quadratic form it does no matter what definition you follow.
