Cabtaxi number

In number theory, the n-th cabtaxi number, typically denoted Cabtaxi(n), is defined as the smallest positive integer that can be written as the sum of two positive or negative or 0 cubes in n ways.[1] Such numbers exist for all n, which follows from the analogous result for taxicab numbers.
