Between October 1961 and October 1989, the former Soviet Union conducted 340 underground nuclear tests at a site near Semipalatinsk, Kazakhstan. A statistical analysis of the times and dates of those tests suggests that the favorite numbers of the test site commanders may have had a significant influence on the precise timing of the detonations.
