Dear Detlew,

interesting; I will chew on it time allowing. ;-)

» BTW2: The runs test is implemented via normal approximation like the implementations in the R-packages tseries or lawstat. The drawback is that it by design will give only approximate p-values for such small lists as discussed here. If these approximate values are conservative or liberal I don't know.

In my aged program I used exact values for N ≤200 according to

Tables for testing randomness of grouping in a sequence of alternatives
Ann Math Statist 14, 66–87 (1943)

These tables are reproduced in the “Wissenschaftliche Tabellen Geigy 3” p165, 8th Ed 1983. If you you don’t have them let me know and I will send you a scan.

Part of the tables at Google books.
