Hi, Whenever I use the invisible comma on symbolic input, Mathematica makes the comma visible in the output. I'm curious about how to keep the comma invisible. I was wandering through the Mathematica Formula Gallery and saw the demonstration "Product of two five-dimensional totally antisymmetric tensors" and was wondering how in the world did they manage to generate that (I would think, in the demonstration of all of Mathematica's power, they did not have a person just type the whole thing out). Upon cutting and pasting the entire expression into a cell and fiddling with the formats and styles and such, I discovered that they had used invisible commas, because they all became visible! As it turns out, it wasn't too difficult to make a program that would generate the product of antisymmetric tensors with an arbitrary number of indices in terms of all the delta's; it only took one line! But no matter how I defined it, with visible or invisible commas, they came out all visible. Is there a formatting option that would allow control of this? Again, I'm pretty sure that the ones who designed the gallery did not in fact try to replace an enormous amount of visible commas and make them invisible. I know that just about any aspect of formatting in the front end can be controlled, but getting lost in that Option Inspector is something I do frequently :-) thanks, Chris -- Chris Tiee "Choni" | Primary email: choni at home.com Alternate emails: choni at cyberjunkie.com, ch0ni at hotmail.com Sent via Deja.com http://www.deja.com/ Before you buy.
