You’re flagging the claim:

“The Sadratnamālā of Śaṅkara Varman (Kerala, 1819) gives the circumference of a circle of diameter 10¹⁷ parts as 314,159,265,358,979,324 — π correct to seventeen figures — encoded in one verse via the kaṭapayādi consonant-to-digit cipher and computed with the Kerala school's series methods. Whish reported it to the Royal Asiatic Society in 1834. Europe held longer digit records by then; the claim is the encoding and the unbroken lineage, not the record. ”
