What is the Difference between Fourth and Fifth normal form?

Note: - There is a huge similarity between Fourth and Fifth normal form, i.e. they address the problem of “Multi-Valued facts”.

“Fifth normal form” multi-valued facts are interlinked and “Fourth normal form” values are independent. For instance in the above two questions Supplier/Product and Supplier/Location are not linked. While in fifth form, the Dealer/Product/Companies are completely linked.
