Maple uses sequences, lists, sets, tables and arrays for representing more
complicated data. See `?sequences`, `?list`, `?set`,
`?table`, `?array` for more detailed help and examples.
A sequence is a sequence of expressions separated by commas.
The `seq` function is a very useful function for creating sequences.
It's syntax is

Lists group sequences and are created using square brackets `[, ]`.
Sets are like lists except duplicate entries are removed. Sets are
created using squiggley brackets `{, }`. Examples

> S1 := 1,5,3; S1 := 1, 5, 3 > max(S1); 5 > S2 := seq(i^2, i=1..5); S2 := 1, 4, 9, 16, 25 > S2[3]; 9 > S1 := {x,y,z,y}; S1 := {x, y, z} > S1 union {w,x}; {x, y, z, w} > L1 := [x,y,z,y]; L1 := [x, y, z, y] > L2 := [L1[4],L1[2..3]]; L2 := [y, y, z]
