The covering radius of C is deï¬ned as r(C)=max xâF min yâC+x wt(x), where wt(Â·) denotes the Hamming weight. Bounding the covering radius of codes is one of the main extremal problems of coding theory. Let C ={x â F: (x,c)=0 âc âC} be the dual code of C and (A i,0 â¤i â¤n) be its weight distribution, where A i =|{x âC: wt(x)=i}|and (x,c)denotes the dot product.
Class 4-5 Receivers. These receivers are the heaviest-duty trailer hitches that can be installed at the rear of a tow vehicle. A Class 4 hitch can carry 10,000 pounds and 1,000 pounds of tongue weight with a weight carrying hitch, or up to 12,000 and 1,200 pounds with a weight distributing hitch.Class 5 receivers can carry up to 14,000 pounds and 1,400 pounds tongue weight.eight distributing hitches are used in the same Class 3-5 receivers as a weight carrying hitch. Any vehicle with a Class 3-5 receiver can use a weight distributing hitch. There are a couple of key differences between these units and weight carrying models.
