Sampi

Sampi (Ϡ) is an obsolete letter of the Greek alphabet and has a numeric value of 900 when used as a mathematical character. It may have been derived from the older letter san. The name "sampi" seems to come from [o]sàn pî: "like pi." Another name formerly used for this archaic letter was Disigma because of the phoneme it represented, /ss/ or /ks/.

Sampi is mostly represented in modern writing by a glyph resembling a π slanted rightwards, which is the reason for its name in Modern Greek. In ancient epigraphy, there were other shapes, including one resembling an upright T. The Unicode standard of modern computer encoding has introduced two sets of codepoints for these two usages, both with an uppercase and lowercase variant: T-shaped alphabetic U+0372/U+0373 (Ͳ/ͳ, ), and Π-shaped numeric U+03E0/U+03E1 (Ϡ/ϡ).
