| Aug 10, 2012 at 20:01 | comment | added | Will Jagy | @Anton, using my symbols, in $P' A P = I,$ I have a large number of programs in C++ for manipulating positive integral forms in 3 variables. A few for indefinite forms, then just one in Magma for computing genera. Maybe you should email me, I have a collection of notes, currently about 100 pages, that explains a good deal, while sticking to the language of matrices and quadratic forms. Click on my profile (my name) for instructions to find my two main email addresses. Very good bibliography as well. | |
