COMMENTS

Here a number is called balanced if the sum of digits weighted by their arithmetic distance from the "center" is zero. Since palindromes (A029952) are trivially balanced, they are excluded here.
This is the base5 variant of the decimal version A256075 invented by Eric Angelini. See there, and the base2 version A256082, for further information and examples.
