maybe better if i used the word"confusion"instead of "ambiguity". back to topic: the confusion arises because there is always an integer larger than the other integers,  while "largest heegner number"is very clearly 163. if some point of the construction of a number causes confusion in public/expert's eyes,then this kind of number can be classified as "not well-defined" or  "ill-defined"
