Probably a Primes problem?? | Comment 1 of 7

Taking the string, without the final "x1y1", i.e. 22 ones only, this gives us a number with seven prime factors, one duplicated: (11, 11, 23, 4093, 8779, 21649, 513239) which is said to be the lowest factorization which contains all ten digits (probably not only in English and French but in a language of choice).  I have no idea what the x1y1 means unless we are looking at 26 digit numbers and/or some other than base10 numbers.??  Does this assume some previous problem for interpretation?

(EDIT) The claim that this is the lowest factorization which contains all ten digits, if only for those numbers where all the digits are the same.
