Digit Filters Mirror3 Boxed Pick 2 The Mirror3 Boxed (P34ID:M3-BOX) is a so called "digit filter". A digit filter divides each digit into options. The Mirror3 filter has the following options:
Mirror3 = Digits 0 = 7 1 = 8 2 = 9 3 = 0 4 = 1 5 = 2 6 = 3 7 = 4 8 = 5 9 = 6
The addition "Boxed" (BOX) refers to the fact that in this case the position within the result is of no interest. So the filter string is always sorted in ascending order.
