Nemesis is a small set with 55 commons, 44 uncommons, and 44 rares. These numbers are normal for a small set of this era. Foil cards are included in booster packs with advertised odds of 1 : 100 cards. The set was printed in Belgium. The existence of USA-printed Nemesis is unknown. 
Nemesis was sold in 15 card booster packs. Booster boxes have 36 packs.
The Belgian printing uses striped collation with 10 × 11 sheets and 12 × 11 sheets. Packs are back-facing and contain 3 uncommons, 1 rare, and 11 commons (in that order). Foil cards are inserted only between stripes (in other words, after a card on the left side of the sheet before moving all the way back to the right), displacing a card of the same rarity.

There is a single 10 × 11 common sheet that contains each common card twice. It has been reconstructed by observing pack openings. The top row presented here is chosen to prevent blue cards for appearing next to each other on the sheet.
There is a single 12 × 11 uncommon sheet that contains each uncommon card three times. It has been reconstructed by observing pack openings. The top row presented here is chosen to prevent blue cards for appearing next to each other on the sheet.
 The "Compilation of Manufacture Information for MTG Products" thread on the Magic Librarities Forum lists US-printed Nemesis as uncertain. I also did not find any during my research.
