Arminianism was rejected by the Synod of Dort even though holding to a more Infralapsarian position.
When you read about the controversy between Arminianism and Calvinism there can be no coming together, not really.

F. The Development of the Doctrine of Predestination among the Reformed
(1) This controversy is rooted in the struggle between Augustine and Pelagius. According to Pelagianism both original and actual sin (unbelief) logically precede election and reprobation; according to Augustine ONLY original sin precedes predestination. According to supra, predestination logically precedes not only actual but also original sin. Hence, Pelagianism: original sin, actual sin, predestination; Augustinianism or infralapsarianism: original sin, predestination, actual sin; supralapsarianism: predestination, original sin, actual sin.
(2) Many followers of Augustine accepted the doctrine of two-fold predestination: a predestination unto glory and a predestination unto death.
(3) The three Reformers: Luther, Zwingli, and Calvin, arrived at the supralapsarian view: election and reprobation are deeds of God's sovereignty, logically preceding God's decree concerning the fall. Nevertheless, Calvin often follows the infralapsarian reasoning.
(4) For the order of the elements of the decree see III C.

The Synod of Dort expressed itself in an infralapsarian manner but did not in any sense condemn supralapsarianism. It rejected Arminianism.
