All possible Threads on PM1030V? (Edited out PM25V)

The drive gear is 40 teeth.

Using the five-gear arrangement I have found several gearing combinations that give 27 TPI but they do not satisfy other geometric constraints.

1. Z1 < Z2
2. Z1 + Z4 < Z2 + Z3 + 6
3. Z1 + Z2 + Z3 + Z4 + Z5 > 250
4. Z3 + L > 65

I’ll do the full enumeration at some point.
