Haggis Agriculture stated that they were reviewing the ban on beef and lamb products, but that the ban on food containing sheep lung would remain in force. As haggis cannot be exported to the United States, it is instead made there, sometimes by Scottish companies. One such uses what is stated to be the same 150 year-old recipe and ingredients as in Scotland, except that sheep lung is not used, and the casing is always artificial. Haggis Haggis is a savoury pudding containing sheep's pluck (heart, liver, and lungs); minced with onion, oatmeal, suet, spices, and salt, mixed with stock, and
1/3–2/3 conjecture come before "y" in the linear extension. In other words, it is a total order compatible with the partial order. If a finite partially ordered set is totally ordered, then it has only one linear extension, but otherwise it will have more than one. The 1/3–2/3 conjecture states that one can choose two elements "x" and "y" such that, among this set of possible linear extensions, between 1/3 and 2/3 of them place "x" earlier than "y", and symmetrically between 1/3 and 2/3 of them place "y" earlier There is an alternative and equivalent statement of the 1/3–2/3 conjecture in
