@MichaelE2 That's what I found out by accident when I tried to install my Symbol Information Palette on V8 and nothing worked :-(

@kirma Not really :)

Module[{vc, fi},
 {vc, fi} =
  PolyhedronData["Octahedron", {"VertexCoordinates", "FaceIndices"}];
 GraphPlot3D[
  Graph[DeleteDuplicates@
    Flatten[UndirectedEdge @@@ (Sort /@
          Partition[#~Append~First@#, 2, 1]) & /@ fi]],
  VertexCoordinateRules -> vc, PlotStyle -> Thick]]

Why it doesn't plot as an octahedron?

@kirma Possibly because you've not done the same delete dupes + sort operation on the VC rules

Check this:

GraphPlot3D@Graph@DeleteDuplicates@Flatten[UndirectedEdge @@@ (Sort /@
    Partition[#~Append~First@#, 2, 1]) & /@ Last@PolyhedronData["Octahedron", {"VertexCoordinates", "FaceIndices"}]]

@rm-rf What I explicitly want is sphere embedding, that's the reason for VertexCoordinateRules... omitting it certainly helps things in some scenarios. (Mine, of course, is simplification of a bit complicated scenario...)

Hello people

G'day Rojo

@kirma All good?

Does anyone know if there's a question somewhere about replacing consecutive sequences of symbols in a list according to some rule, efficiently?

@kirma Yeah... I didn't fully check what VCR was doing here. I don't see why what you're doing shouldn't work.

@Rojo I think so, Friday evening and all! :)

Meaning, given {{0,1}->"a", {3, 5, 6}->"b"} and {0,1,3,5,6,0,1}, get {"a", "b", "a"} for example

@rm-rf I'm feeling a bit similarly, but probably fi and vc do render right, according to the values... but is there an inconsistency between indices used in those two PolyhedronData attributes?

@kirma I don't think so... It clearly has dropped the 2 <-> 4 and 3 <-> 5 edges

@rm-rf To me it looks more like it has permuted some edges. Just swap two edges and it should be correct!

@kirma Not sure I follow...

@rm-rf Well, the crossing on the middle shouldn't occur anyway.

anyway, time for more beer ->

Hi there!

Anyone around?

I can't seem to find a post about how to locally define options for a built-in function... InheritedBlock works, whough with minor flaws, so I was looking for a confirmed, more stable way. If there exist one.

Hi, what do I search to find questions (even tangentially) related to looking up thinks like "all ids wich have $value as $property" in things like { {id1 -> {prop1 -> val1, prop2 -> val2}, id2 -> {prop1 -> val1, ... }} or should I stop search and just use Cases and/or hook up a db?

Main problem with Cases is that I can't use Dispatch. although it seems silly to expect mathematica to behave like a db

@IstvánZachar I've used InheritedBlock wihtout problems, but I guess it wouldn't be much work to create a function that localizes the options

@ssch I'm guessing you're using the API? Perhaps not an answer to your question, but this is certainly worth reading

We are talking about dynamic localization, right?

@rm-rf Project gutenberg :) That is neat! Ended up putting it in postgresql though
