 OFFSET 0,2 COMMENTS After 12 hours or 43200 seconds, the hands overlap at 12:00 and the cycle repeats. LINKS Table of n, a(n) for n=0..36. Mathlete's Corner, How many times during the day do the hands of a clock overlap? Index entries for linear recurrences with constant coefficients, signature (1,0,0,0,0,0,0,0,0,0,1,-1). FORMULA a(n) = round(n*43200/11). EXAMPLE For n=1, 3927 would correspond to slightly after 01:05.
