parasitic number


Given a base b integer n with k digits d1,,dk (with d1 being the least significant digit), and an integer 1<m<b, if it is the case that

m(i=1kdibi-1)=d1bk-1+(i=2kdibi-2),

then n is called an m-parasitic number or m-left-transposable number.

If one takes an m-parasitic number, concatenates copies of its digits in order whatever number of times one wants, the resulting new number will also be m-parasitic.
