%N Number of 'prime' groundstate 3ball juggling sequences of period n.
%C This sequence counts the length n asynchronic site swaps given in A084521/A084522.
%C A juggling sequence is defined as 'prime', if it does not visit any state more than once. This means that in A084523 no integer occurs twice between consecutive sevens.
