Wanted to add my two-cents into the discussion. I have exhaustively listed H3 cells from resolution 1 to resolution 6 before I reached this issue...I would like to share the...

@sahrk I included all the valid indexes, so at resolution 4 there are 12 pentagons. For odd-numbered resolutions there are more non-hexagons (pentagon, heptagon, octagon, decagon), but the distribution of...

@sahrk So for those cell with more than 6 edges, there might be several edges connecting to the same neighbour cell? Okay...(I will have to verify that later on) That's...

@sahrk More results after my message on Mar 22, on whether pentagon is included/excluded. Probably due to the broken symmetry, maximum area always occurs at base cell 2 or 119,...

I would suggest adding a h3IsNotHexagon() function as it is not just pentagons. Another point I want to add (but I don’t think that demand any change in the current...

@nrabinowitz Really thanks for the clarifications and hope these all go into the upcoming documentation updates.

I am trying to exclude that the long latency of the zmm variant is related to the the preceding instructions of the ymm variant... "instructions":[ {"inst":"vfmadd231ps xmm, xmm, xmm" ,"lat":...

It is probably not an AVX-512 issue as such situation seems only limited to AVX-512 FMA instructions: vpmaddubsw xmm, xmm, xmm : Lat: 3.70 Rcp: 0.53 vpmaddubsw ymm, ymm, ymm...
