Re: [tlaplus] How to get a set like this in TLA+?

Hello,

using TLC for evaluating the constant _expression_ [1]

{{xx, yy, zz} : xx \in 1 .. 2, yy \in 3 .. 4, zz \in 5 .. 6}

produces

{ {1, 3, 5},
{1, 3, 6},
{1, 4, 5},
{1, 4, 6},
{2, 3, 5},
{2, 3, 6},
{2, 4, 5},
{2, 4, 6} }

Is this what you had in mind?

[1] Note that TLC will complain if the base sets are not homogeneous, for example if you mix integers and strings.

Hello I'm a newbie in TLA+.

I knew that Cartesian product is something like this:
S × T × U = {<<a, b, c>> : a ∈ S, b ∈ T,c ∈ U }.

And I wonder how can I get a set like this:
{{a, b, c} : a ∈ S, b ∈ T,c ∈ U }.

Thank you.
