Reply To: Alphabetical Divisions with Headings and Displayed Material – Blank Lines
It would be helpful to see a picture of a few entries from the material in question. Without seeing it, your formatting seems good. If the displayed material is math (rather than just text) and you are working in UEB with Nemeth, no blank line is required before and after it.
Alphabetic divisions don't require blank lines, but a cell 5 heading requires a blank line before it so there would need to be a blank line between an alphabetic division and a cell 5 heading.
