Thanks for the clarification, Bob. The code is in MUMPS (or M as it is also called). Outside the U.S. it is used mostly in business applications, while inside the U.S. it is mostly used in medical settings.

I take it to mean 1-1 correspondence in that any VIER with more than
one matching NEUN is discarded, likewise any NEUN matching more than
one VIER. So for example VIER=1369 is eliminated because it pairs
with 4624 and 5625; NEUN=1521 fails as it matches 4536 and 7056.
All but the one solution pair can be thus deleted.
