About Some Relatives of the Taxicab Number
Abstract
The taxicab number, 1729, has the following property. If we add its digits we obtain 19. The number obtained from 19 by reversing the order of its digits is 91. If we multiply 19 by 91 we obtain again 1729. In the paper we study various generalizations of this property.
