Really good thread !
Can you post the practical thing(A example from the block) to people get more Knowledge on this

go to a block explorer like blockchair.com and sort the blocks based on the number transactions inside like this:
https://blockchair.com/bitcoin/blocks?s=transaction_count(asc)#f=id,transaction_count,merkle_root
then start from 1 tx and compute the merkle root yourself to learn how it works (when it is only one, merkle root is the same as tx hash). you should do this by opening the link to that block and copying its transaction hashes (keep in mind hash strings in bitcoin are reported in reverse order)
then move the count higher to 2 transactions and do the same computation then move it to 3 transactions and finally move it to 4 transactions and repeat calculation for the last time.

now you know almost all the cases and anything more than this number is mostly repetition of the same thing.
