Back Matterred by and are an outgrowth of the remarkable Brandt-Intrau tables of reduced positive ternary forms , published in pre-computer days after what must have been an incredible amount of effort. The Brandt-Intrau tables serve not only as a model of accuracy but also as a starting point for generatin
