Tihai ending pattern.  The tihai is based on this pattern.

EH:  dzzddzzd zddddzd

This pattern has length 15.  To find the gap length g, we solve the equation 3*15 + 2*g = 1 (mod 7).  The smallest value of g that makes this equation true is 6, since 3*15 + 2*6 = 57 = 1 (mod 7).

So EH z6 EH z6 EH  has duration = 1 (mod 7).
