Discovery index (ConceptTopic, 3)

From Hi.gher. Space

The discovery index is a canonical indexing system for assigning unique identifiers to new discoveries until enough data has been collected to properly classify them. This index provides an unambiguous identifier to refer to new discoveries without needing to commit to a particular classification or naming scheme, which may not be accurate at initial discovery time since there may not yet be enough data at the time to determine how to classify and name them.

This page serves as the authoritative list of discovery index (or D-number) assignments. All new assignments should be added here first before being used anywhere else. New assignments should have been verified (preferably by multiple researchers) to be correct before being added here.

The index field should be a link to a page that describes the discovery in detail, unless it has been named, in which case its name (in the comment field) can serve as the link.

The classification field is intended to indicate the eventual classification of the discovery, and may be left blank initially.

The comment field is intended to give a brief description of what the discovery is, and should simply be its name, if one has been given. Otherwise, in lieu of its name, the broad category it is (possibly temporarily) assigned to, or, barring that, a brief description of its shape or something to differentiate it from the other entries. The comment field is not intended to be a verbose description of everything about that discovery; that should go into the discovery's own page.

The current assignments are:

D4.1 Segmentochoron Snubdis antiprism
D4.2.x Ursatope Catch-all category for ursachora, grandfathered from old CJ indexing system
D4.3.1 Bilbirothawroid Castellated rhodoperihedral prism
D4.3.2 Bilbirothawroid Castellated rhodopantohedral prism
D4.4 Bilbirothawroid Triangular hebesphenorotundaeic rhombochoron
D4.4.1 Bilbirothawroid Tetraaugmented triangular hebesphenorotundaeic rhombochoron
D4.4.2 Bilbirothawroid Diminishing of D4.4.1, such that six bilbiro's and two thawro's occur.
D4.5.1 Bilbirothawroid Diminished triacontasphenorotunda (tentative name)
D4.5.2 Bilbirothawroid Triacontasphenorotunda (tentative name), non-diminished version of D4.5.1
D4.5.3 Bilbirothawroid Modified remainder of rectified 120-cell after a D4.5.2 has been cut off from it
D4.5.4 Bilbirothawroid Compressed version of D4.5.3 that introduces J91 cells

D4.12 Augmentation of 600-cell 144° wedge to produce a pentagonal orthocupolarotunda cell.
D4.13.1 Modification of a 600-cell 120° wedge to produce two J92 cells.
