Formation

Chii toitsu

This yaku does not combine with chii toitsu. By definition, chii toitsu is formed by the collection of seven pairs. Although, ryanpeikou may be interpreted as a collection of seven pairs also. However, ryanpeikou is actually composed of sequences, rather than as independent pairs. The pattern simply appears as a collection of pairs.

With chinitsu

Some forms of ryanpeikou mixed with chinitsu and tanyao may actually form some optional yakuman, named daisharin (pinzu), daichikurin (souzu), and daisuurin (manzu).
