Summary edit

Description
English: A partially ordered set in which the bounds of the 1/3–2/3 conjecture are exactly met, factored as a series composition of 1-element and 3-element partial orders. According to a result of Aigner ("A note on merging", Order 2 (1985) 257–264, doi:10.1007/BF00333131) this is the only extreme case for width-two partial orders.
