A115159 purports to be numbers which are not the sum of a nonnegative
triangle, square and cube.
However, every listed element is indeed such a sum, starting with:
34 = 10+16+8
63 = 55+0+8
89 = 45+36+8
99 = 91+0+8
139 = 10+121+8
...
and I could supply the rest on request. In fact, I could find no
nonnegative integers <= 50000 that are in
the sequence, and I would venture that every nonnegative integer is a
such a sum.
