1986: David Wells: Curious and Interesting Numbers:
- The Dictionary
- $8042$
Mistake
Correction
- $(1) \quad$ This should probably read:
- as we have:
- $8042 = 1^3 + 4^3 + 4^3 + 10^3 + 10^3 + 10^3 + 17^3$
- among many other expressions.
- $(2) \quad$ Also note that:
- $8042 = 1340^3 + 1338^3 + \paren {-1339}^3 + \paren {-1339}^3 + 2^3$
- so what it really ought to say is:
This entry has been excluded from Curious and Interesting Numbers, 2nd ed. of $1997$, so perhaps it was not even true in the first place.
