Re: [tlaplus] How to convert a Sequences to a set efficiently

Hi The Anh,

if you want to construct the set of the elements (i.e., the co-domain) of a sequence you can define

Range(s) == { s[i] : i \in DOMAIN s }

Of course, you lose the information on the order and the multiplicity of the elements in the original sequence.

Hope this helps,

Stephan
