The 11-part doesn't stand up to this sort of analysis (or rather the one 
that resulted in the figure 4356). Each part generates a different 
number of 4-runs varying from 253 in the penultimate part up to 399 in 
the last part. I'm afraid my method for counting these is just to put 
all the rows into a spreadsheet and do some string processing. It turns 
up the same figure of 3456 for the 12-part.
