In mathematics, a covering system (also called a complete residue system) is a collection
of finitely many residue classes whose union covers all the integers.
For any arbitrarily large natural number N does there exist an incongruent covering system the minimum of whose moduli is at least N? |

Famous quotes containing the words covering and/or system:
“We have good reason to believe that memories of early childhood do not persist in consciousness because of the absence or fragmentary character of language covering this period. Words serve as fixatives for mental images. . . . Even at the end of the second year of life when word tags exist for a number of objects in the childs life, these words are discrete and do not yet bind together the parts of an experience or organize them in a way that can produce a coherent memory.”
—Selma H. Fraiberg (20th century)
“In the course of the actual attainment of selfish endsan attainment conditioned in this way by universalitythere is formed a system of complete interdependence, wherein the livelihood, happiness, and legal status of one man is interwoven with the livelihood, happiness, and rights of all. On this system, individual happiness, etc. depend, and only in this connected system are they actualized and secured.”
—Georg Wilhelm Friedrich Hegel (17701831)
