<text, standard> (BMP) The first plane defined in
Unicode/ISO 10646, designed to include all scripts in
active modern use. The BMP currently includes the Latin,
Greek, Cyrillic, Devangari, hiragana, katakana, and Cherokee
scripts, among others, and a large body of mathematical,
APL-related, and other miscellaneous characters. Most of
the Han ideographs in current use are present in the BMP,
but due to the large number of ideographs, many were placed in
the Supplementary Ideographic Plane.

<text, standard> (SIP) The third plane (plane 2) defined in
Unicode/ISO 10646, designed to hold all the ideographs
descended from Chinese writing (mainly found in Vietnamese,
Korean, Japanese and Chinese) that aren't found in the {Basic
Multilingual Plane}. The BMP was supposed to hold all
ideographs in modern use; unfortunately, many Chinese dialects
(like Cantonese and Hong Kong Chinese) were overlooked; to
write these, characters from the SIP are necessary. This is
one reason even non-academic software must support characters
outside the BMP.

In the Unicode standard, a plane is a continuous group of 65,536 (216) code points. There are 17 planes, identified by the numbers 0 to 16, which corresponds with the possible values 00–1016 of the first two positions in six position hexadecimal format (U+hhhhhh).

Absolute geometry
Absolute geometry is a geometry based on an axiom system for Euclidean geometry without the parallel postulate or any of its alternatives. Traditionally, this has meant using only the first four of Euclid's postulates, but since these are not sufficient as a basis of Euclidean geometry, other systems, such as Hilbert's axioms without the parallel axiom, are used. The term was introduced by János Bolyai in 1832. It is sometimes referred to as neutral geometry, as it is neutral with respect to the parallel postulate.
