Thank you for the good examples, they are usefull to me. I think these, 
and other, examples should be included to in the documentation that 
is available from the F1 help key in a windows wxMaxima installation
for Contents Chapter 37 "Lists". 

Also in chapter 37 doc there should be a "see also" cross reference list.
The list would contain something like [lmax(l), lmin(l), sort(L,P), subst(a,b,c),...etc..] 
These are functions, defined in other chapters or packages, that important 
or useful for working lists. Maybe the subject is cross reference lists
