What is a collection or a great number of baskets called?
Solution 1:
Not specific to baskets, but generally applicable to any manufactured item (often used in a production context), one option is Batch:
a group of things or people dealt with at the same time or considered similar in type: The cook brought in a fresh batch of homemade cupcakes. We looked at the job applications in two batches. (Cambridge.org)
From the same context, but also generally applicable: Lot:
an amount or set of things, especially when there are several of these amounts: I've already done one lot of washing. Another lot of visitors will be here this afternoon. (Cambridge.org)
Both of them are used to reference a particular "set" of items that were manufactured or processed at the same time or in the same location, to distinguish them from other similar (not to say apparently identical) sets:
Batch number is also referred to as “lot number”. Recording of the batch and batch number typically starts at the manufacturing plant. Batches should be maintained and recorded according to:
- Quantity
- Manufacturing cycle
- Expiry date
- Weight of the active ingredient
- Excipient(s) (lfatabletpresses.com)
