Net topology

pcu

Demonstration record from the development seed — not production data.

JSON · mfpx

1 vertex and 3 edges in the unit cell. 3 of them leave the cell and continue into a neighbouring one; those are drawn in the accent colour and end at a hollow node. Squares are vertices of coordination 5 or more, circles of 4 or fewer. Drag to rotate, or focus the figure and use the arrow keys.

Catenated
not recorded
Not recorded: no source we read states whether this net is interpenetrated. The RCSR Systre archive carries no catenation field at all, so a record built from it alone says nothing either way. A blank here is that absence, not the claim that the net is not catenated.

Canonical key

Systre key
3 1 1 -1 0 0 1 1 0 -1 0 1 1 0 0 -1
(rcsr)The canonical Systre key, copied verbatim from the local RCSR Systre archive of 2019-06-01. It is not computed here and cannot be: no Gavrog/Systre toolchain runs on this machine, so nothing on this site derives, extends, repairs or verifies a key. The checksum served beside it is the one the archive itself carries, copied from the same block, so that this copy can be checked against the upstream file; no checksum is computed or verified here.

Vertices

No corroboration of the coordination-sequence mapping is recorded on this record, which was not written by the provenance-tracked ingest. The sequences are shown as the record stores them, unchecked.

One row per distinct vertex. The coordination sequence counts how many vertices lie at each topological distance; the vertex symbol names the shortest ring at each angle of the vertex. The two columns do not carry the same warrant: which of them was corroborated, and which was not, is stated above the table.

Position in the collection

RCSR index
1536 (derived) Derived by this site, not published by RCSR: the 1-based position of the symbol in the ascending ASCII-lexicographic ordering of the 2930 symbols in the RCSR Systre archive of 2019-06-01. RCSR does not number its nets; this is our ordering of their symbols and nothing more.
Complexity rank
1 The order the ingest processed this net in, simplest first. A different number from the RCSR index above, meaning a different thing.
