| | Taxicab Number -- from Wolfram MathWorld |
 | | The first few taxicab numbers are therefore 2, 1729, 87539319, 6963472309248, 48988659276962496,... |
 | | Hardy and Wright (Theorem 412, 1979) show that the number of such sums can be made arbitrarily large but, updating Guy (1994) with Wilson's result, the least example is not known for six or more equal sums. |
 | | Sloane defines a slightly different type of taxicab numbers, namely numbers which are sums of two cubes in two or more ways, the first few of which are 1729, 4104, 13832, 20683, 32832, 39312, 40033, 46683, 64232,... |
