A062682 is "Numbers that are sums of consecutive cubes in more than 1 way."
First of all, it should be "consecutive positive cubes", e.g. we don't
count (-1)^3 + 0^3 + 1^3 + 2^3 + 3^3 and 2^3 + 3^3 as different ways.
Moreover, I think it should be "more than one consecutive positive cubes"
as we don't include 6^3 = 3^3 + 4^3 + 5^3. The data given include 77053284,
which I think I can prove is the sum of consecutive positive cubes in only
one way (144^3 + ... + 164^3).
