蝦夷方言藻汐草

Iwan rikop remains the lexical candidate, supported by iwan ‘six’ and the documented star word rikop in Hattori's Bihoro column and Batchelor. The corrected transcription イワンリユプヽ and its final apparent iteration mark remain visible; the ユ／コ discrepancy is unresolved. Iwan riyup, iwan riyupu and iwan riyupupu are literal spelling comparisons without independent lexical support, so they do not replace rikop in the modern reading. Nojiri's Pleiades identification depends on interpretations of Moshiogusa and is not an independent attestation. The whole name and precise star identification remain a guess.
