A060768 Pseudo-Kaprekar triples: q such that if q=x+y+z, then q^3=x*10^i + y*10^j + z, where (y*10^j+z < 10^i) and z < 10^j. 4

COMMENTS
True Kaprekar triples (A006887) must have j=n and i=2n, where n is the number of digits in q.

EXAMPLE
134^3=2406104 and 134=24+06+104. 134 is not a Kaprekar triple since the three terms of the sum would need to be 2, 406 and 104. 134 is not a term of A328198 because one addend (06) begins with '0'.
