Such is Erdős' acclaim among some mathematicians, that an 'Erdős number' is particularly prized, which is equal to the academic degrees of separation to Erdős. For example, the mathematician himself has a value of 0, mathematicians who coauthored a paper with him have a value of 1, those who coauthored a paper with them have a value of 2, and so on. | Such is Erdős' acclaim among some mathematicians, that an 'Erdős number' is particularly prized, which is equal to the academic degrees of separation to Erdős.
