A hexagonal shape (cristallography)

Adjective

1. (geometry) Having six edges, or having a cross-section in the form of a hexagon.

   Nuts in engineering are generally hexagonal.

   • 2023 November 9, Christopher Ingram, ““Weathergami” charts paint new portrait of Minnesota climate”, in Minnesota Reformer‎^[1], archived from the original on 25 August 2026:

     If we just plopped down a dot for every observation we’d end up with an undifferentiated black blob, so the weathergami technique visualizes frequency of temperature pairs: we divide the chart area into a fine hexagonal grid, and then color each hexagon according to how many daily observations fall within it.

2. (crystallography) Having three equal axes which cross at 60° angles, and an unequal axis which crosses the others at 90° angle.
