Comments

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.

Examples

			The successive site swaps are: 3; 4,2; 4,4,1; 5,2,2; 5,3,1; 4,4,4,0; 4,5,3,0; ... See A084522.
		

Crossrefs

The number of such site swaps of length n is given by A084529. First position where n appears: A084527.

A084503 Binary juggling state vectors (given in decimal), associated with the three balls juggling sequence A084501.

Comments

This sequence counts the length n asynchronic site swaps given in A084521/A084522.
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.
