Not expressible as x^3+-x^2

[Pfoertner, Hugo]

Seqfans,

this one seems not to be in OEIS:

Numbers not expressible as sum or difference of a cube and a square, x,y
notequal 0:

6 14 21 27 29 32 34 42 46 51 58 59 62 66 69 70 75 77 78 84 85 86 88 90 93 96
102

Found by brute force search, please check & extend.

Thanks

Hugo
