We construct three nonsingular threefolds , and with vanishing irregularities. has Kodaira dimension and its -canonical transformation has the following property: the minimum integer number , such that the dimension of the image dim for , is given by . and have Kodaira dimension and their -canonical transformations have the properties: dim if and only if , dim if and only if or .
