Suuankou
Suuankou 「四暗刻」 is one of the standard yakuman hands. This hand consists of four concealed triplets and a pair, i.e. none of the triplets must have been claimed from other players' discards. If the hand is on a shanpon wait, the winning tile must be a tsumo and not as a discard of another player. A win by discard may render the fourth triplet as an "open" triplet. Thus, the condition for the yakuman would not be met.

Then there is suuankou tanki 「四暗刻単騎」, which features the hand with a tanki wait, the winning tile may come from another player's discard. In this case, all four triples are present in the hand. This hand is closed only.

Value
This hand is automatically a yakuman hand, won by tsumo using a shanpon (tenpai holding two pairs) or any win if using a tanki (one tile waiting for a duplicate). Variable rules may allow the tanki version to count double that of the yakuman points, if won via tsumo.

Formation
All four of the triplets must be concealed for this hand to be counted as a yakuman. Tile calls of closed kans are acceptable, as the closed kan also counts as a closed triplet. The difficulty of this yakuman stems from the need to draw at least 3 out of 4 of a single tile type, for four different tile types. Discard calling to attain tiles immediately removes any chance of forming this yakuman.
With a shanpon wait, one of the pairs is upgraded into a triplet. If this method of completion is done by discard, then that fourth triplet is considered to be "open". So instead of yakuman, the hand would instead be counted as a combination of toitoi and sanankou, at least.
