Abstract:
1. A method for sorting an object in a sorter having N rows, the object entering the sorter in a current row, the method comprising the steps of: (A) setting a first crossover switch to one of a straight position that does not change the current row of the object, and a cross position that switches the object to a row having a binary representation with a parity opposite that of a binary representation of the current row; (B) passing the object through the crossover switch to a new current row; (C) transferring the object from the current row to a new current row having a binary representation that is a circular rotation of a binary representation of the current row; (D) setting a next crossover switch to one of a straight position that does not change the current row of the object, and a cross position that switches the object to a row having a binary representation with a parity opposite that of a binary representation of the current row; (E) passing the object through the crossover switch to a new current row; and (F) repeating steps (C) through (E) a total of log
