Daisharin 「大車輪」 refers to a group of three optional yakuman. To achieve daisharin or its variants, you need a closed hand that contains: 22334455667788, all of the same suit. As optional yakuman, they may or may not be included in the game.
The yakuman named "daisharin" itself refers to this pattern with pinzu; daichikurin 「大竹林」 and daisuurin 「大数隣」 apply to souzu and manzu respectively. Calling a hand with souzu as "daisharin" would be incorrect. However, while they are technically three distinct yaku, a ruleset that includes the pinzu daisharin will usually implicitly include daichikurin and daisuurin as well.
Pattern
The pattern for daisharin differs only in which tile is used to win the hand, and will always have at least one yasume tile:
Agari: Yasume:
The same applies to daichikurin:
Agari: Yasume:
and daisuurin:
Agari: Yasume: 
Scoring
When classified as distinct yaku, daisharin and company are awarded yakuman. Even if they are not used, however, than hands are worth at least a 10-han baiman:
- Tanyao: 1 han
- Ryanpeikou: 3 han
- Chinitsu: 6 han
The high score that this hand naturally achieves helps to explain why it is uncommonly scored as yakuman.
