In 1507 he took up his residence in the Benedictine Abbey of St Germain des Pres, near Paris; this was due to his connexion with the family of Brigonnet (one of whom was the superior), especially with William Brigonnet, cardinal bishop of St Malo (Meaux).
According to Aimoin of SaintGermain-des-Pres, and the chronicler, Richer, he was a Saxon, but historians question this statement.
D x the first evectant; and thence 4cxdi the second evectant; in fact the two evectants are to numerical factors pres, the cubic covariant Q, and the square of the original cubic.
The discriminant of f is equal to the discriminant of 0, and is therefore (0, 0') 2 = R; if it vanishes both f and 0 have two roots equal, 0 is a rational factor of f and Q is a perfect cube; the cube root being equal, to a numerical factor pres, to the square root of A.
His open advocacy of Jansenist opinions, however, caused his superiors to relegate him to the most obscure houses of the order, and finally to keep him under surveillance at the abbey of St Germain-des-Pres at Paris.
