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

Swed FS and C Eisenhart
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, 8^th Ed 1983. If you you don’t have them let me know and I will send you a scan.

Part of the tables at books.
