| They are in this one, and it appears correct to me:

|
| A really nice web-app for searching and animating _passing_
| siteswaps is: https://passist.org/
|
| For example: https://passist.org/siteswap/9968926?jugglers=2
|
| In case of confusion: the diagram with arrows is a _" causal
| diagram"_, showing the throw that is forced by each throw. So
| linking arrows are not the same ball/club, and the arrows can go
| backwards in time(!).
|
| passist.org will animate solo siteswaps:
| https://passist.org/siteswap/915?jugglers=1 -- but 915 is
| animated really high by default. Click on the animation, then the
| cog, then increase the juggling speed, rather than the animation
| speed, to bring the pattern down lower.
|
| There's also an android app that does similar stuff:
| https://github.com/namlit/siteswap_generator

| I specifically enjoy this comment:

| mistake which made the smaller men juggle at twice the rate of
| the larger men. This halves the quality of the smaller men's
| animation, but I left it because I rather liked the smaller men
| juggling faster the smaller they got.

| archive wrapping.)

| events that I know of.

| Thanks so much for the IJDb Colin E!

| This is using something called Sitewap notation
| https://en.wikipedia.org/wiki/Siteswap Each throw is
| represented by a number. Roughly speaking, a number X in the
| pattern implies that the throw is the "normal" throw when
| juggling X balls. So a normal pattern for 5 balls is just "5".
| One necessary but insufficient property is that the numbers in
| the pattern have to average to the number of balls you're
| juggling.
| LanceH wrote:
| The pattern described in the initial link is "915". That means
| throwing a ball to the height of a 9 ball pattern (the height
| you would throw if juggling 9 balls normally), next ball to a 1
| ball height (essentially handing it across), then the third
| throw is to a 5 ball pattern height.
|
| Then you repeat -- starting with the other hand.
|
| The three heights add up to 15, with 3 throws in the sequence,
| so this is a pattern to be juggled with 5 balls.
|
| A three ball sequence would be written as "3". "333" would be
| the same thing as it is just a repetition of the same "3"
| sequence.
|
| Even numbers are thrown to the same hand.
|
| There are more advanced notations for throwing two at the same
| time, or for a pause, and I'm not sure what a "2" would
| represent (hold in same hand one beat maybe).
