Source for ⇑ ⤊ ⟰ and ⇓ ⤋ ⟱

The arrows ⇑ ⤊ ⟰ and ⇓ ⤋ ⟱ are found in the same source as the ad hoc Go symbols ⚆, ⚈, ⚇, ⚉. As the latter symbols are only attested from that source, according to people who have searched the Unicode documents (see the sources in the notation section of w:Go_(game)), it is possible that the motivation for including these multiple arrows is at least partially that source or the one it was based on (John Conway, per Berlekamp & Wolfe (1994:18)). If they have other uses as well, which are too much to squeeze in here, we might want to split them off into their own articles. kwami (talk) 10:34, 17 March 2023 (UTC)

Possible missing Translingual mathematical sense

See Signed zero, where it is given as some sort of limit notation. Equinox ◑ 03:11, 7 September 2023 (UTC)
