Writing forms
Icosa notation combines registered terms through explicit forms. This page is a map to the governing Canon records; the linked rules and compositions remain authoritative.
Write a cell as two concatenated letters, capacity then domain. Separate a list of cells with commas; do not put a comma inside a cell. Do not join cells with a slash or an underscore, and do not write state with colons. Magnitude uses 0 for centered or a signed digit 1–3, never a repeated sign.
