The original 82S173 predated the JEDEC JESD3 standard for PLD fuse
data, so numbers weren't assigned. They probably just kept

Excellent. That is exactly what I was trying to find. Thank you.
Would have been nice
there is a better diagram on page 70 of
981-0251_ProgrammableLogicDiagramPackage_Sep90.pdf
under dataIO which gives the fuse number

A Signetics PLS173 PLA has a total of 2178 programmable fuses:
(32 AND gates for logic terms plus 10 AND gates for control terms)
times
(24 true/complement inputs plus 20 true/complement inputs/outputs)
= 1848 fuses
(10 OR gates)
times
(32 AND gates logic term outputs)
= 320 fuses
10 fuses for
