Dear Sara,
In my understanding there is only one "empty list", which is [], the list with no elements.
If you mean a list with 76 elements, each of which are "blank", you could use something like
L:makelist(null,76);
null isn't anything special in Maxima. It is just a variable name to which (I guess) you have assigned nothing yet.
Using something like null, rather than 0, enables you to later tell the difference between a blank element and another which has been actually set to "0" (it is one of your examples below).
Anyway, I hope this makes sense.
Chris

Subject: an empty list with 76 elements
Hello,
I made a list like A with elements from 0 until 7.5:
A : makelist(i*0.1, i, 0, 75);
equal to this list I need as well an empty list with the same size.
I would like to know please how to make a "empty" list with for
example 76 elements?
Thanks and best regards
Sara
