Order dimension

Summary

The order dimension of a partially ordered set is the least number of linear extensions whose intersection is the given order. It measures how far the order is from being total: total orders have dimension 11. Equivalently, it is the least dd such that the poset embeds in a product of dd chains with the product order.
