When this dotted net is folded into a die, what is the total number of dots on the four faces that share an edge with the one-dot face?

In the row 1 3 6 4 the squares one apart are opposite, so 1 is opposite 6. The four faces sharing an edge with 1 are all the others except 1 and 6: $21-1-6=14$. (20 forgets to leave out the opposite face.)
