# --description--
A [taxicab number](https://en.wikipedia.org/wiki/Hardy–Ramanujan number "wp: Hardy–Ramanujan number") (the definition that is being used here) is a positive integer that can be expressed as the sum of two positive cubes in more than one way.
Un [numero taxicab](https://en.wikipedia.org/wiki/Hardy–Ramanujan number "wp: Hardy–Ramanujan number") (la definizione che viene utilizzata qui) è un intero positivo che può essere espresso come la somma di due cubi positivi in più di un modo.
The first taxicab number is `1729`, which is:
Il primo numero di taxi è `1729`, che è:
1<sup>3</sup> + 12<sup>3</sup> and
1<sup>3</sup> + 12<sup>3</sup> e
9<sup>3</sup> + 10<sup>3</sup>.
Taxicab numbers are also known as:

</ul>
# --instructions--
Write a function that returns the lowest `n` taxicab numbers. For each of the taxicab numbers, show the number as well as its constituent cubes.
Scrivi una funzione che restituisce i numeri di taxi più bassi `n`. Per ciascuno dei numeri taxicab indica il numero e i suoi cubi costituenti.
