Is it possible for someone to provide the roller coaster maplesim model?

The latest quick update fix for a bug is the fastest fix I have seen in a long time.  A nice surprise actually.

In my travels I happened to come across this ... "Since then, we’ve successfully released a new build of Wolfram|Alpha’s codebase each week, incorporating not only hundreds of minor behind-the-scenes enhancements and bug fixes, but also a steady stream of major new features and datasets."  taken from here

I'm not sure this topic has ever come up.  I cannot find a way to output strikethrough characters.  Underline and subscript will get you strikethrough characters.  Is there a way to produce strikethrough output?

The verticies are of a 4x4 square, 16 in total.  You may cross a verticie only once, and you can move horizontally, vertically and diagonally.

Lets label the verticals  a,b,c,d and from bottom to top 1,2,3,4.  How would you find all the routes with a travel length of 6?

Some plotting options only allow view option.  Is there another way to specify axes ranges?

In a BubblePlot, I want to display only a portion of the graph.  view works fine for single graphs no problem, but when I combine it in display with multiple graphs I don't want the unviewed portions in Bubbleplot re-appearing.  

for example

with(Statistics):
with(plots):
a := BubblePlot([4, 5, 2, 3], [1, 2, 7, 8], [8, 1, 3, 2],view=[default,4..9])
