The early Moda charm packs had varying totals of squares, from 30 to 40 or so, but they all seem to have 42 now. Layer cakes are 40-42. Duplicate prints depend on the fabric line, some lines have more designs and colorways than others.
Some manuf. (Benartex, RJR, Hoffman etc) have fewer total squares /strips, so you either get fewer prints or more duplicates, in my experience.
