The transitivity r and s are computed by nothing in this project: they count the faces and the tiles of a natural tiling, and none is derived here. That is a measured limit rather than a job not yet done. The Gavrog library this project runs Systre from was tried on 2026-09-12: for a 3-periodic net it has no route from a net to a tiling at all, and for a 2-periodic net it has one that works, whose result is a plane tiling with faces and no tiles and so a transitivity triple rather than an r and an s. This block therefore states p and q and leaves r and s unknown rather than filling them. Every entry carries the tool, its version and input_checksum, the checksum of the graph that was actually analysed, so that a result computed from the graph this record holds now can be told from one computed before it changed. Nothing here rebuilds a graph to check that, so no entry below is claimed to be current.","periodicity":{"rcsr-archive-key":{"basis":"rcsr-archive-key","basis_note":"the RCSR archive key, the canonical key the archive states","status":"ok","reason":null,"tool":"mofpp.periodicity","tool_version":"1","input_checksum":"sha256:72e2ea87848c344ee404f1adcca403fcd6cb435759db27f4c30bd9f0d9947170","seconds":0.00019493396393954754,"computed":"2026-09-11T17:20:58.056924","dimension":2,"periodicity":2,"connected":true,"interpenetration":1,"catenated":false,"undetermined_reason":null,"component_count":1}},"symmetry":{"rcsr-archive-key":{"basis":"rcsr-archive-key","basis_note":"the RCSR archive key, the canonical key the archive states","status":"ok","reason":null,"tool":"systre","tool_version":"19.6.0 sha256:0d272e98a1a21669bc67a809b95c014ba2a2fb39a6fd2147039201216ab0d48d options:--systreKey wrapper:2","input_checksum":"sha256:72e2ea87848c344ee404f1adcca403fcd6cb435759db27f4c30bd9f0d9947170","seconds":0.156,"computed":"2026-09-12T00:01:25.366645","connected":true,"component_count":1,"describes_one_net":true,"scope":"Systre found one connected net in the repeat unit, so the group, the kinds of node and edge, and the key below describe that net.","dimension":2,"multiplicity":1,"point_group_order":6,"node_kinds":3,"edge_kinds":5,"repeat_unit_factor":1,"repeat_unit_accurate":true,"space_group":"p6","space_group_setting":null,"space_group_number":null,"plane_group_number":16,"td10":255,"degrees_of_freedom":5,"rcsr_identification":"fwd","systre_key":"2 1 2 0 0 1 3 0 0 1 4 0 0 1 5 0 0 2 3 0 0 2 6 0 0 2 7 0 0 3 8 0 0 3 9 0 0 4 5 0 0 4 10 0 0 4 11 0 0 5 12 0 0 5 13 0 0 6 7 0 0 6 11 1 0 6 14 0 0 7 10 0 0 7 15 0 0 8 10 0 1 8 13 1 0 8 14 0 0 9 11 0 1 9 12 0 0 9 15 -1 1 10 15 0 0 11 14 -1 0 12 13 0 0 12 15 -1 1 13 14 -1 0","warnings":[],"key_matches_archive":true,"key_matches_archive_reason":null,"components":null}},"invariants":{"rcsr-archive-key":{"basis":"rcsr-archive-key","basis_note":"the RCSR archive key, the canonical key the archive states","status":"ok","reason":null,"tool":"mofpp.invariants","tool_version":"2","input_checksum":"sha256:72e2ea87848c344ee404f1adcca403fcd6cb435759db27f4c30bd9f0d9947170","seconds":0.015672359964810312,"computed":"2026-09-11T17:20:58.057988","shells":10,"td10":255.0,"td10_reason":null,"genus":null,"genus_reason":"genus is defined for 3-periodic nets; this graph is 2-periodic","repeat_unit_factor":1,"repeat_unit_factor_source":"an archive key is Systre's canonical key, built on the minimal repeat unit"}},"rings":{"rcsr-archive-key":{"basis":"rcsr-archive-key","basis_note":"the RCSR archive key, the canonical key the archive states","status":"ok","reason":null,"tool":"mofpp.rings","tool_version":"2","input_checksum":"sha256:72e2ea87848c344ee404f1adcca403fcd6cb435759db27f4c30bd9f0d9947170","seconds":0.0887833870947361,"computed":"2026-09-11T23:11:48.973373","max_ring":40,"net_point_symbol":"(3.5^2.6^3)2(3^2.5^2.6^2)3","net_point_symbol_reason":null,"classes":[{"vertices":[0,13,14],"cycle_symbol":"3.3.5.5.6(2).6(2)","vertex_symbol":"3.3.5.5.*.*","point_symbol":"3^2.5^2.6^2","coordination_sequence":[4,8,12,20,22,26,32,36,46,44],"capped":true,"reason":"2 angles have no ring of at most 40 edges"},{"vertices":[1,4,5,6,11,12],"cycle_symbol":"3.3.5.5.6(2).6(2)","vertex_symbol":"3.3.5.5.*.*","point_symbol":"3^2.5^2.6^2","coordination_sequence":[4,8,11,20,26,26,32,38,43,47],"capped":true,"reason":"2 angles have no ring of at most 40 edges"},{"vertices":[2,3,7,8,9,10],"cycle_symbol":"3.5.5.6.6.6","vertex_symbol":"3.5.5.6.*.*","point_symbol":"3.5^2.6^3","coordination_sequence":[4,10,14,18,22,29,34,36,41,47],"capped":true,"reason":"2 angles have no ring of at most 40 edges"}],"capped":true}},"checks":{"name_match":"single-source","name_match_reason":null,"vs_corroboration":null,"vs_corroboration_superseded":null,"vs_topology_mismatch":null,"cs_row_check":null,"catenated_name_heuristic":null,"spacegroup_handedness":null,"rcsr_identification":null,"conflicts":{}}},"curation":[],"citation":{"text":"MOF++ contributors (2026). fwd [net].
